I know how to open multiple mat files, using

filename = uigetfile('*.*', 'All Files (*.*)','MultiSelect','on');

But this returns a cell array with the file names that I selected. How would I access these files names for the information stored within them?

One thing to be careful of, however, is if files have similar variables. For instance, if two files have the variable x, then after running the for-loop, you will only have the value(s) for x of the last file that was loaded. To combat this issue, consider using

data{n} = load(filename{n});

or something similar to store the data.
