matfile_listvar

Arguments

fd

Real: file descriptor (returned by matfile_open).

names

String vector: names of the variables.

classes

Real vector: classes of the variables.

types

Real vector: data types of the variables.

Description

Lists variables of a Matlab binary MAT-file opened by matfile_open.

Returns empty matrices if the file contains no variables.

Examples

A = rand(10,10);
B = sprand(100,100,0.1);
C = "foo";
D = "bar";
savematfile('test_matfile.mat','A','B','C','D','-v6');
clear();
fd = matfile_open("test_matfile.mat");
[name, classes, types]=matfile_listvar(fd);
matfile_close(fd);

for i=1:size(name,"*") do
disp("The variable " + name(i) + " has type " + string(types(i)) + " and class " + string(classes(i)))
end
