I see. If Jos is correct, then you can also do this with a slight modification of the solution I gave earlier.


[m,n] = size(A);
Rr = npermutek(1:n,m); % The "Row-Rank" matrix.
G = A((Rr-1)*m+repmat(1:m,n^m,1));

IIRC, COMBN and NPERMUTEK do the same thing using different methods.

Dear Ozge!

And if speed matters, the C-mex VChooseKRO might be helpful also:
