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?

load(filename{1}); %to load the contents of the first file
load(filename{2}); %to load the contents of the second file
...
%and so on

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.

Perfect, I actually was trying to figure out how to combat that, thanks!.
