listvarinfile
lists variables stored in a binary archive (names, types, sizes..)
Syntax
listvarinfile(filename); [names, typs, dims, vols] = listvarinfile(filename)
Arguments
- filename
a character string, the pathname of the file to be inspected.
- nams
a matrix of strings, names of the variables saved in the file.
- dims
a list, dimensions of the variables saved in the file.
- typs
a numeric matrix, types of the variables saved in the file.
- vols
a numeric matrix, size in bytes of the variables saved in the file.
Description
This utility function lists "a la whos" the variables stored in a Scilab data file created with save.
 | Rationals and state-space linear systems are reported as plain tlists |
Examples
// Preparing some data of various types: b = rand(2,3) < 0.5; // booleans i = uint64(grand(3,4,2,"uin",0,100)); // hypermatrix of encoded integers c = grand(3,3,"uin",-10,10); c=c+c'*%i; // complex numbers p = (1-%z).^(0:3); // polynomials r = p/(1+%z); // rationals sp = sprand(10,15,0.1); // sparse numbers spb = sp<0.5; // sparse booleans t = ["This" "software" ; "is" "Scilab"];// Texts g = [gdf() gda()]; // Graphics function Test() // macro disp("listvarinfile() test for macros") end M = linspace; // macro L = list(%f, int8(-23),, %i-%z, list("abc",%e)); // simple list C = {"abc" %t ; %z list(1/%z, 4)}; // array of cells S(4,2).r = %pi; // array of structures vars = list("b","i","c","p","r","sp","spb","t","g","Test","M","L","C","S"); // Archiving data in a binary file: File = TMPDIR + "\listvarinfile.sod"; save(File, vars(:)) // Listing the file content: [names,types,dims,vols] = listvarinfile(File); types(find(names=="Test")) dims(find(names=="i"))
