MATLAB: Extract Variable from Filename

You can use strtok() or other methods, but I prefer regexp here:

    filename = 'sitename.yr.synth.daily.mat'  %example
    pieces = regexp(filename, '\.', 'split');  %divide by periods
    sitename = pieces{1};

MATLAB: Application of “csvwrite(filename,M)” with different filename

See: FAQ: process a sequence of files. And if you are there already, ready the other topics also.

FilePath = tempdir;
for i = 1:10
  FileName = sprintf('file%02d.dat', i);
  FID = fopen(fullfile(FilePath, FileName), 'w');
  if FID == -1, error('Cannot open file for writing'); end
  fprintf('%g %g\n', rand(2, 2));
  fclose(FID);
end

The reading works equivalently.

Instead of using files to carry the input data, you can use the data directly in the next iteration.
