From: tiziana Franchin on 13 Jul 2010 16:24 Dear all, I've a 31x256871 matrix and I need the correlation coefficients, but the size exceeds the maximum allowed. Where can I download a MATLAB script for solving this resctriction? Thank you

If not, I would strongly advise you to do so. Roger Stafford

MATLAB computes correlations among the rows. On the off chance that you really want correlations among the columns, you could transpose the matrix before passing it into corrcoef. -- Tom
