MATLAB: Subscript indices must either be real positive integers or logicals

Question

Hi

I have a (huge) matrix A which I have loaded in my workspace, which does contain numbers between -13.286 and 12.456 etc. Now upon applying X = corr(A) I get the following error:

>> Subscript indices must either be real positive integers or logicals

..what can I do?

Answer 1

Very likely you have a variable in your system called 'corr' which conflicts with the matlab function of the same name.
