How to calculate correlation separately

Hiya,

Thank you for developing such a wonderful tool!

I need to calculate the correlation between two matrixes, M (with m lines) and N (with n lines), that is, the correlation of M1-N1, M1-N2, M1-N3,......, Mm-Nn.

To do so, I have to put M and N together, then I'll need to do (M+N)^2 correlations with many 'junk data'. So, I'm wondering if you have a simple function to calculate eLSA between two variables instead of within matrix. With this, I'll only need to calculate M*N correlations.

Thank you for your help!
