taking the average of data from 500 different files

Hi,

I have 500 different files in sequential filenames in the following format: datafile_XX.mat

All of these files contain a matrix that is of size n x 8. n is changing per file. but there are 8 columns total.

I want to take the average of the first 400 rows of each file. How do i load all of these files efficiently?

for ni = 1:500
  filename = sprintf('datafile_%03i.mat',ni);
  load(filename)
  % Process your stuff here
end
