Finding the average of multiple Matrices on multiple files

I am trying to find the average, max and min of matrices piece by piece, not as a whole matrices. I have tried to use a for loop but I think I am too beginner to make it work. I have 7 files, each with their own matrices that I would like to bring in and average them. Any ideas?

Thank you!

What do you mean piece by piece? column by column?

An example:

folder='E:\Matlab';
filetype='*.xls';  % or xlsx , specify the correct format of your files
f=fullfile(folder,filetype);
d=dir(f);
for k=1:numel(d);
  data{k}=xlsread(fullfile(folder,d(k).name));
Average{k}=mean{k};
end

Read processing sequence of files for better understanding.
