A = rand(10, 10);
B = sprand(100, 100, 0.1);
savematfile("test_matfile.mat", "A", "B", "-v6");
clear();
fd = matfile_open("test_matfile.mat");
matfile_listvar(fd)
matfile_close(fd);

//fd = matfile_open("test_matfile.mat", "w"); // Empty test_matfile.mat

//fd = matfile_open("test_matfile.mat", "w", "7.3"); // Empty test_matfile.mat as a Matlab 7.3 file
