Creating a function that gives the size and name of the variables in the mat-file

Hi, I am trying to write a function that gives the size and name of the variables in the mat-file

I have this:

S = whos('-file','workspace313.mat')

% lists in alphabetical order the names, sizes, and types of all variables in the currently active workspace.

for k = 1:length(S)

disp([S(k).name, mat2str(S(k).size)]

How do I go on?

Try this:

d = dir('*.mat'); % Get a list of all .mat files in the current folder.
for k = 1 : length(d)
	s = load(d(k).name) % Load it.
	names = sort(fieldnames(s)); % Get fieldnames and sort them.
	for k2 = 1 : length(names)
		fprintf('  File "%s" has a field called %s.\n', d(k).name, names{k2});
	end
end
