matfile_varreadnext
Reads next variable in a Matlab binary MAT-file.
Calling Sequence
[name[, value[, vartype]]] = matfile_varreadnext(fd)
Arguments
- fd
Real: file descriptor (returned by matfile_open).
- name
String: name of the variable read or
""
if reading failed.- value
Any Scilab type: value of the variable read or an empty matrix if reading failed.
- vartype
Real: type of the variable if reading succeeds or:
0: if the variable type is unknown.
-1: if end of file has been reached.
Description
Reads next variable in a Matlab binary MAT-file opened by matfile_open.
Examples
A = rand(10,10); B = sprand(10,10,0.1); C = "foo"; D = "bar"; savematfile('test_matfile.mat','A','B','C','D','-v6'); clear(); fd = matfile_open("test_matfile.mat"); //-- Loop on the stored variables while %t [Name, Value, Type] = matfile_varreadnext(fd); if Name == "" then break; else disp("The variable " + Name + " has type " + string(Type) + " and contains:"); disp(Value); end end matfile_close(fd);
