Matrices of real or complex numbers were poorly displayed.genlib and library help pages were outdated concerning Scilab 6.cumsum() improved.mtlb_sparse() removed from the documentation.frameflag=9 and strf=".9." values of these plot2d options were no longer accepted. Their documentation was ambiguous.TODO keyword was no longer highlighted.user is removed for a while but was still documented.setfield page: The output and the 6.0 history were documented only on the en_US version. The input was wrongly restricted to matrices, while any Scilab object is acceptable. The specific role of setfield for mlists was not really described nor illustrated. The example did not include any call to setfield.covStart(["isempty" ; "isscalar"]) crashed Scilab.getdate page: The time referential was obscure: a) UTC for Unix Time Convention vs Coordinated Universal Time. b) unclear influence of the time zone.get page needed to be overhauled: get(0), get(0,prop), get(tag), get(tag,prop) and other features were not documented.gsort was unable to sort any hypermatrix along dimensions > "r"|"c".gsort: the only sparse possible input were real or complex vectors, and only with the g method.intersect supported neither sparse boolean nor sparse numeric inputs.unique could not process 2D sparse matrices.setdiff(s,s2) yielded an error when s or/and s2 is sparse encoded.mfile2sci abusively added a 6 lines mode(0); ieee(1) header to every converted file.[].figure_name crashes Scilab.(m:n)($) crashed Scilabisequal(1:$, 2:$) returned %T.covStart() clear previous coverage information. profileEnable() could be used to append a macro later on.covStart() help page was incomplete about the API usage.assert_checkequal() did not considered equal matching Nan or void elements in (nested) containers.typename() still considered removed uncompiled macros (11, "m"), and "mc" overloading code instead of "function".wavread was wrong.unwrap() failed unfolding curves with straight segments.[U,km,ku] = unique(..) was not implemented.setdiff("","") produced "" instead of []. The "c" and "r" options yielded an error for string inputs. Input arguments were poorly checked.strcat() was much slower in Scilab 6.0.2.isdef([],..) yielded an error instead of returning [].script2var did get variables generated by exec().median(m,"r") and median(m,"c") yielded wrong results (6.1.0 regression)plot([0 1], ":") plotted a dash-dotted curve instead of a dotted one.msprintf() did not handle LaTeX dollars anymore.Simulation => Modelica initialize displayed "Undefined variable: flag" in the console.csvRead() was crashing with CSV files containing empty lines.(m:n)(:) crashed Scilabmtlb_zeros([]) was crashing Scilab.external_object_java class was crashing Scilab.edit_curv yielded an error when reading data.toJSON(var, indent, filename) is the right call sequence. Documentation has been updated.asciimat(text) did not accept strings of different lengths or including some extended UTF-8 characters.colorbar(..) ignored how to guess umin and umax for a Champ object (with .colored="on").setdiff(a,b,"r"|"c") with a and b boolean yielded an error.setdiff(sparse([1 3 0 2]), sparse([3 7])) missed returning 0, and wrongly returned 3.gsort yielded an error when sorting any sparse vector including some NaN.mean() did not handle sparse numerical matrices.imult(%z) crashed Scilab.issquare was not overloaded.getdate page should be rewritten: a) getdate("s") does NOT take leap seconds into account. b) D=getdate(X) is vectorized, accepts fractional seconds and returns them in [0,1) in D(10) instead of milliseconds. Moreover, the time referential of the result was unclear (time zone, daylight saving offset).clock returned none of the milliseconds, time zone, and daylight saving time.csvTextScan() and csvRead() did not handle well complex data.1 ./ uint8(0) crashes Scilab (idem with int8, uint16, int16, uint32, int32, uint64, int64).getdate("s") truncated the actual time to integer seconds. getdate(u)(10) returned fractional seconds instead of milliseconds as getdate().bitget(x,pos) and bitset(x,pos) results could be wrong when pos is an encoded integer.soundsec(t,freq) has the trivial equivalence 0 : 1/freq : t*(1-%eps) and should be removed.deff could not return the created function as output argument, preventing to create and use anonymous functions. The function's headline and body had to be provided separately. For Simple functions, a one-string input (possibly console-oriented) definition was not supported.mapsound needed to be reforged.fplot2d is weaker than plot and useless. It should be removed.num2cell returned {} for any input array of empty strings.mfile2sci conversion of ispc and isunix still used MSDOS removed far ago. Conversion of ismac was missing. Conversion of exist missed using mtlb_exist. Conversion of dos yielded some "operation +" warnings. Unit tests for the conversion of cd, dir, and ferror overwrote some Scilab reserved keywords. Conversion of return yielded mtlb(resume).unique(["" ""]) returned ["" ""].macr2tree + tree2code translated e={2} into "e=1" and e={2,"ab"} into "e=[2,"ab"]".isempty(A) was true for a sparse matrix of dimension 2^16 or larger.histplot(-10:0.2:10, 2) yielded a warning from histc and an error.edit(user_defined_function) corrupted the original code.mfile2sci did not support Matlab block-comments %{ ..%}.** was undocumented.mfile2sci had several issues when converting the NOT ~ operator: 1) ~(1-1) was converted into ~1-1 instead of ~(1-1) 2) ~ applied to an integer expression yielded an error from convert2double 3) ~i was converted into ~%i instead of ~abs(%i).mfile2sci: Some axis conversions were wrong or not reliable.mfile2sci: The prettyprintoutput flag badly managed appended comments.%i|[], []|%i, %i&[], and []&%i were wrong. %t|%i, %t&%i, and %i&%t were not defined.libmatio >= 1.5.18 was not supported.union did not support input boolean, sparse boolean, nor sparse numerical matrices. The result of union(complexA, complexB) was wrongly conjugate.bitcmp needed to be upgraded for Scilab 6..*. operator, kron() was not defined for sparse numeric matrices..*. nor kron() worked with boolean or sparse boolean matrices.gamma did not support incomplete gamma integrals.close could not close the help browser, xcos, nor the variable editor or browser.derivat had no reciprocal polyint polynomial integration function.inv could no longer be overloaded for hypermatrices of decimal or complex numbers.rand(2,2,2)^2 yielded a wrong result instead of trying to call the %s_p_s overload for input hypermatrices.fullfile badly handled any forced final file separator when building a directory's path.== and <> between libraries were no longer defined.importgui function's name was not explicit enough. importgui is renamed uiSpreadsheet. importgui internals was public.interp1's documentation did not tell the spline edges conditions; extrapolation modes were poorly explained; the description of the result's size was completely wrong; x as an option was not documented. periodic and edgevalue extrapolation modes were not available. linear extrapolation was not available for splines. When xp is an hypermatrix with size(xp,1)==1, the size of the result was irregular/wrong.det(sparse) most often yielded Nan. [e,m]=det(sparse) was not actually implemented.getcolor had a bunch of issues.atomsInstall and atomsRemove did not update the Toolboxes menu.input("message:") yielded a wrong error message about mprintf in case of non-interpretable input.interp was leaking memory.x=spzeros(1e10,1e10) yielded an incorrect error message.diag(spzeros(2,2)) yielded an Operation -[] warning.help echo could not redirect to help mode when preferred, for new users coming from Octave.atomsInstall was flashing many times on the console.get_function_path("acosh") yielded an error (regression from Scilab 6.0.0).m2sci code converter needed a set of fix and improvements.asciimat("A";"";"B") yielded a transposed matrix of codes. When processing an hypermatrix of codes, the dim#2 of the result was squeezed (unlike Matlab/Octave's behavior).strsplit('a','a'), strsplit('ab','ab'), and strsplit("abcd","cd") yielded wrong results.spec documentation used messy concurrent notations. It still refered to the Arnoldi module instead of eigs. The fr_FR version was incomplete.mgetl could not read from stdin.prettyprint export to html failed under Linux and macOS.fullpath failed to resolve the path depending on pwd.bitget did not accept positive integers of types int8, int16 or int32.datafit algorithm was not documented.circshift introduced.factorial could use a huge memory amount even for a scalar argument.lstsize was a duplicate of size and should be removed.datafit help page needed to be fixed and overhauled.champ1 is useless. champ().colored is available for a long time.ged did not allow moving several objects.gsort could not perform multilevel sorting, and could not sort complex numbers completely.[ny,nx] of meshgrid(x,y) results and usages with graphics was not enough documented.definedfields wrongly considered as defined void elements in lists, tlists, and mlists.list2vec and vec2list were located in the optimization module instead of in data_structures, and were missing in the See also section of list.isdef and definedfields had mismatching answers for void elements in lists, mlists, or tlists.unique was not able to return the number of occurrences of returned distinct entities.SCALE_CSCOPE & SCALE_CMSCOPE in Xcos.disp puzzlingly displayed arguments in reverse order.sciargs() included twice -nw when -nw is used.assert_checkequal(list(1,,3), list(1,,3)) yielded an error.: operator was too lowDominationRank could be made private in optim_nsga2.isinf was not reliable for polynomials.gca().axes_bounds refered to fig.figure_size instead of fig.axes_size.colorbar, retrieving the handle of the new color bar was not trivial.subplot's action was unclearly described on its help page. Page improved.show_window() did not raise the current graphics window.bitset did not work for numbers greater than 2^32-1.toprint was not translated.strcmpi was an obsolete duplicate of strcmp(,'i'). It is removed.plot(1:3, 10) failed.unsetmenu() for a dockable="off" figure crashed Scilab.get_figure_handle was a specific duplicate of the more powerful findobj('figure_id',n) feature. It is now obsolete..figure_size were not documented.plot2d(), plot() did not accept logflags among input arguments.mgeti wrongly handled int64 or uint64 integers bigger than 2^52. The mget/mgeti help page was unclear.clc(0) did nothing, now clears last console entry. Remove leading blank after a clc().size([],3) returned 1 instead of 0.strsubst crashed on consecutive occurrences.csim failed when the system has no state.size([],3) returned 1 instead of 0.Demo > GUI > Uicontrols 2 could not be exported to a file.closeEditvar() had to be replaced with editvar("close").emptystr is 40x slower with 6.0.0 wrt 5.5.2bench_run was too strict about the specification of tests names.[names,mem]=who() was always zero.x = ric_desc(H,E) always yielded an error. [x1,x2,residual] = ric_desc(..) returned a wrong residual value.bitset worked only element-wise, without accepting mixed scalar and array inputs.dec2base was 53-bit limited by double and not uint64 readysimulated_annealing module was out of the optimization one.genetic_algorithms module was out of the optimization one.hist3d was not an histogram function. It is renamed bar3d.[m,e]=log2(x) was not documented. As public function frexp was in duplicate with [m,e]=log2(x).mprintf, msprintf a non-finite number displayed nothing.sleep 1 crashed Scilab.exportUI on a non dockable figure crashed Scilab.function replacing mc for functions in the Scilab language was not documented.msprintf segmentation fault was caught due to a wrong size.xmi files saved from Xcos could not be opened by drag & dropping them into the console.size(sum(ones(2,3,4,5),4)) was [4 2 3] instead of [2 3 4].weekday yielded an error for some row of input dates.lsqwas leaking memory.sci2exp was no longer able to convert non-scalar structures.xgetech was poor and stiff compared to any combination of gca() properties .axes_bounds, .data_bounds, .log_flags, and .margins. It is removed.bitget needed to be upgraded.eval was a weak duplicate of evstr. It should be removed.lu was leaking memory.ric_desc should be merged into riccati.atomsGetInstalledPath returned "" if the provided technical name differs only by the case, or is a fragment, or failed when the version is not provided.twinkle was not able to blink several independent objects.numer and denom were poor and duplicates of the .num and .den fields of rationals. They are removed.freson silently returned frequencies not corresponding to a maximum, or returned [] instead of some still computable maxima frequencies.comet and comet3d did not allow specifying colors with colors names.nicholschart plotted nothing. The default frame color was a flashy cyan. The position of gain labels could be puzzling. It was not possible to specify colors by their names. Postprocessing the frames and the set of labels was not easy.a .*. b failed when a or b or both are hypermatrices, with one or both being polynomials or rationals.repmat was slow. Its code did not use kron and was complex.[] and its non-convertibility were poorly documented.lucene 4.10 in Debian.scatter and scatter3d failed when specifying a single data point.set documentation page needed to be overhauled.factorial could be used up to only n=170.unique was not able to consider all Nan values as the same value.

There was no flag for cases with an infinite number of solutions. When there is no solution, some values were returned anyway, instead of []. In this case, the documented definition of the err value was dubious. Decimal numbers and integers were accepted, but not encoded integers. Inf and NaN input coefficients were not rejected.fac3d and fac3d1 were still in Scilab 6.0 despite they were tagged obsolete 14 years ago in Scilab 4.1gsort could not sort completely dense matrices of complex numbers.grand(1,"prm",m) yielded an unsqueezed size([size(m) 1]) hypermatrixoverloadname internal macro defined in CACSD was a duplicate of typeof(,"overload"). It is removed.scatter3 function name was an unfounded naming exception. It had to be renamed scatter3d.scifunc_block_m block: any < in the expression was not displayed on the block's icon.^ hat page wrongly indicated that ^ applied to a rectangular matrix not being a vector is done element-wise.xlabel, ylabel, zlabel, and title needed to be upgraded.EXPRESSION block was more expected in the Mathematical palette.plot(x,y) did not accept y as encoded integers.setdiff(1,[]) was [] instead of 1. setdiff(a,[],..) was not enough tested.msprintf("%d", %nan) did not return Nanwavread(..,'info') had a mistake. The wavread page deserved some improvements.writewav page in English said that input data are one column per channel, instead of one row per channel. In addition, in case of writing error, savewave kept the output file open and locked.EXPRESSION, CLR and DLR Xcos blocks did not (always) correctly display multicharacter exponents in expressions displayed in their icons.wavread kept the wav file open and locked when returning on errors. It weakly managed the input file name. It claimed for invalid data formats instead of unsupported ones, with poor information about the current format vs the supported ones. Several error messages referred to a wrong function.group regressed in 5.5.2 due to a too intrusive fix.mfile2sci yielded an unsuitable warning when converting atan.mfile2sci converted acoth using atanh and yielding a wrong warning message.intdec example was biased and not robust when changing sampling frequencies.colorbar(umin, umax) did not work after plot3d2.[struct() struct()] crashed Scilab.x.a=1; x(:)=[] x.a was an empty list.intg(a,b,f) called f(x) with x outside [a,b].polarplot(x,Z) yielded an error when x is a vector and Z a matrix.tand([-90 90]) answered [Nan Nan] instead of [-Inf, Inf]. cotd([-90 90]) answered [Nan Nan] instead of [0 0]. 1 ./cosd([-90 90]) answered [Inf -Inf] instead of [Inf Inf].atanh, neither the documentation pages nor the m2sci converter was up to date.intdec(intdec(x, r), 1/r) was most often different from length(x).w=ssrand(2,3,4), []+w, []-w, w+[] and w-[] yielded an "operation +/- []" warning.plot(,"color",c) no longer supported standard abbreviated color names c like "k" for black.tbx_make did not allow easily to force building all toolbox sections without the toolbox builder (if any). tbx_make(Dir,"*") now does it.tbx_make(Dir,'localization') did not update .mo files from .po.prettyprint(complex(1,%nan)) omitted the "+" in 1 + Nani. Documentation was also improved.prettyprint did not support input encoded integers.prettyprint was broken for cells.part("",$) and part("",$-1:$+2) yielded an error instead of returning "" and " ".prettyprint did not allow to export of objects into HTML.x=1:1e10 freezed Scilab.prbs_a was poor and unclear.[].coth was more than twice slower than 1./tanh(). tanh and coth did not accept sparse-encoded input.lstcat could not concatenate input lists with mixed objects of types>10 like 1:$, sin, sind, struct, cells, tlists or mlists. In addition, it was slow for very long inputs lists.assert_checkequal did not support properly or at all Nan and void in lists, Nan in sparse, implicit lists, macros, libraries, built-in functions, graphical handles. For input arrays or lists of matching typeof and sizes, the failure message displayed neither the index nor the values of the first mismatching elements.isglobal was not supporting a non-scalar array of strings as input.%s <> (1+%s) returned %F.tree_show was broken cells within containers.tree_show void components were displayed as non-empty.sci2exp({}) result could not be executed.tree_show needs improvements.uiDumpTree() interpreted "\n" "\r" "\t" sequences in contents as special ones.base2dec() did not detect invalid numbers.playsnd on Windows for a long sound, it was not possible to stop it.playsnd could not be run in a non-modal (asynchronous) way on Linux and MacOS.auread and auwrite kept the sound file open and locked when returning on errors. They poorly handled the default .au sound file extension.playsnd could not directly accept an audio file and could not repeat the input sound.clc(n) cleared n+1 lines instead of n>0. Thus, it was not possible to clear only one line.integrate and intg default absolute tolerances atol was no longer the same. integrate's default relative tolerance rtol was not the same in the case of 3 or 4 input arguments.setPreferencesValue is a general usage function and deserved to be renamed xmlSetValues.fullpath did not support symbolic links in pathss, s([]) returned [] instead of sparse([]).flipdim(hypermat,dim,sb) yielded wrong results for dim<3 and sb>1, and yielded an error for dim>2.ppol changed values of the third input variable.noisegen() and prbs_a() deserved to be moved to the elementary_functions module, gathered with rand() and grand() in a new elementarymatrices/random help subsection.prbs_a() did not comply with the requested number of switches. The biased number of actual switches was unpredictable, preventing to manage its statistical distribution. The probability of the initial state was biased. For instance, prbs_a(n,0) always returned ones(1,n).noisegen is very poor. It is tagged as obsolete and will be removed from Scilab 6.1.x.test_run always failed.libraryinfo yielded 0x0 matrix of strings for libs without any macro.sci2exp yielded an error for any input macro without output argument.mfile2sci yielded an error on a(end) standing for a($) (Scilab 6 regression).zpk2tf and zpk2ss examples yielded an error.for i=1:$, end crashed Scilab.grand causes a freeze after several consecutive calls when using the default base generator.uicontrol.units = "normalized" property was not described.mfile2sci badly converted the colon : into mtlb(:)EXPRESSION, CLR, and DLR Xcos blocks sometimes displayed multiplied terms ambiguously in their icons.WSCI was not defined as an environment variable and could not be used as %WSCI% in commands sent with host or unix_*.bode and nyquist inline demos did not clear and reset the current axes where to draw, which could yield an error.help scilab page were misleading.MSWin>scilab --help missed displaying some options like -args.., -noatomsautoload, etc.colorbar did not support $ in colminmax, standing for the number of colors in the current colormap.loadmatfile could not read Octave native text data files.perms could freeze the whole computer. It could not ignore duplicate permutations.gsort could not sort booleans.isvector was broken for sparse matrices.blockdiag implemented to replace sysdiag, improved and extended to strings.* and .* multiplications involving a sparse boolean and a double, or involving 2 booleans, were not implemented.nnz was not possible (regression).warning documentation were not up-to-date.loadmatfile was never able to automatically detect the input data format.spzeros(0,n) and spzeros(n,0) were different from sparse(0,0).calendar had no formatted display mode.fsolve(x0, fun, tol) no longer took tol into account.cn, dn, ns, nc and nd Jacobi elliptic functions were not available.hallchart had bugs and a poor rendering.graypolarplot, colorbar displayed an empty ungraduated color bar.log10(x) had wrong dimensions when x is a hypermatrix.dockable="off" and closerequestfcn on figures crached Scilab.conj(sparse(x)) was complex when x is real.mgetl could not read single line data which is greater than ~260,000 characters.tree_show crashed for an input Xcos block.matrix(sparse([]),[0 0]) yielded [] instead of sparse([]).esb=sparse([%t %f]); esb(1,:)=[]; , size(esb) answered [0 2] instead of [0 0] .
