hi, how I can find the correlation of an array?

I found corr, but it is find correlation between each two columns . how I can find the correlation between rows.

are there command find the correlation among more than two rows?

maybe using corr on the transposed array?!

I think you can transpose your matrix like this

for example you have a Matrix >>X=rand(10) then >>X=X';

and then perform "corr" or "corrcoef"

like >>[R]=corrcoef (X);

Rand is just an example, just transpose your matrix.
