Combining Matrices into one

Hi

I have 20 matrices (.mat files) from 20 subjects in the format of 68x68. I would like to combine all of them ito a single MAT file, but that one which reads the following structure 68x68x20?

As of now I've been using the following loop and it reads the following structure 1x29

numfiles = 29;
Ws = cell(1,numfiles);
for k = 1:numfiles
  myfilename = sprintf('subject_%d.mat', k);
  Ws{k} = importdata(myfilename);
end

Can anyone please correct this code?

Kind regards

"I have 20 matrices" are those <68x68 double>? "matrices" implies that. If yes, try

%%
numfiles = 29;
Ws = nan(68,68,numfiles);   % <68x68x29 double>  (20 or 29??)
for k = 1:numfiles
  myfilename = sprintf('subject_%d.mat', k);
  Ws(:,:,k) = importdata(myfilename);
end
