Batch processing of .m files

Hi!

I have a set of .m files with file names in sequence (e.g., 1.m, 2.m,..., 100.m). Each file is having a matrix named X with different values.

Within a common .m file (say BatchPro.m) I wish to call files 1.m, 2.m, .... one by one using a for loop to get the data stored on it (matrix X), so that I can process individual values of the matrix X. How to do this batch process?

I m looking for something like:

S = [];

FileList = dir('*.m'); N = size(FileList,1);

for k = 1:N

   FileList(k); %To call 1.m, 2.m, ...

   S(k) = mean(X); % X is a row vector in stored in 1.m, 2.m, ...

end

You can use EVAL to call the different mfiles, but you should correct whatever got you into the awkward situation of needing to do this.

You cannot start a function or script, when its file is called "1.m". How would the call look like?

?! M-file names must be valid Matlab symbols: Starting with a letter, only letters, digits and the underscore, less than 64 characters.

Therefore this will work:

FileList = dir('*.m');
N = size(FileList,1);
S = zeros(1, N);   % Pre-allocate!!!
for k = 1:N
  File = FileList(k).name;
  copyfile(File, 'myTempScript.m');
  clear('myTempScript');
  run('myTempScript');  % Assuming that the files are scripts
  S(k) = mean(X);
  delete('myTempScript.m');
end
