Matlab M-file to Scilab conversion function
mfile2sci([M-file-path [,result-path [,Recmode [,only-double [,verbose-mode [,prettyprintoutput]]]]]])
a character string which gives the path of Matlab M-file to convert
a character string which gives the directory where the result has to be written. Default value is current directory.
Boolean flag, used by translatepaths function for recursive conversion. Must be %F to convert a single mfile. Default value : %f
Boolean flag, if %T mfile2sci considers that numerical function have been used only with numerical data (no Scilab overloading function is needed). Default value: %T
display information mode
no information displayed
information written as comment is resulting SCI-file
information written as comment is resulting SCI-file and in logfile
information written as comment is resulting SCI-file, in logfile and displayed in Scilab window
Boolean flag, if %T generated code is beautified. Default value: %F
M2SCI (and particularly mfile2sci) is Matlab M-file to Scilab function conversion tools. It tries whenever possible to replace call to Matlab functions by the equivalent Scilab primitives and functions.
To convert a Matlab M-file just enter the Scilab instruction: mfile2sci(file)
where file is a character string giving the path name of the M-file mfile2sci will generate three files in the same directory
the Scilab equivalent of the M-file
the Scilab help file associated to the function
the Scilab function required to convert the calls to this Matlab M-file in other Matlab M-files. This function may be improved "by hand". This function is only useful for conversion not for use of translated functions.
Some functions like eye, ones, size, sum,... behave differently according to the dimension of their arguments. When mfile2sci cannot infer dimensions it replaces these function call by a call to an emulation function named mtlb_<function_name>. For efficiency these functions may be replaced by the proper scilab equivalent instructions. To get information about replacement, enter: help mtlb_<function_name> in Scilab command window
Some other functions like plot, has no straightforward ï¿½quivalent in scilab. They are also replaced by an emulation function named mtlb_<function_name>.
When translation may be incorrect or may be improved mfile2sci adds a comment which begins by "//!" (according to verbose-mode)
When called without rhs,
mfile2sci() launches a GUI to help to select a file/directory and options.
// Create a simple M-file rot90m = ["function B = rot90(A,k)" "if ~isa(A, ''double'')" " error(''rot90: Wrong type for input argument #1: Real or complex matrix expected.'');" " return" "end" "[m,n] = size(A);" "if nargin == 1" " k = 1;" "else" " if ~isa(k, ''double'')" " error(''rot90: Wrong type for input argument #2: A real expected.'');" " return" " end" " k = rem(k,4);" " if k < 0" " k = k + 4;" " end" "end" "if k == 1" " A = A.'';" " B = A(n:-1:1,:);" "elseif k == 2" " B = A(m:-1:1,n:-1:1);" "elseif k == 3" " B = A(m:-1:1,:);" " B = B.'';" "else" " B = A;" "end"]; mputl(rot90m, TMPDIR + "/rot90.m") // Convert it to scilab mfile2sci(TMPDIR + "/rot90.m",TMPDIR) // Show the new code mgetl(TMPDIR + "/rot90.sci") // Load it into scilab exec(TMPDIR+'/rot90.sci') // Execute it m=rand(4,2); rot90(m,1)
