Opening/loading multiple mat files?

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

Since the number of files is variable, would something like this work a little better?

for n=1:length(filename)
    load(filename{n});
end

Yes, a for-loop can work well here. I was simply demonstrating the syntax of calling the load function.

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!.
