This is a faster implementation of MATLAB's corr2. Implemented as a mex-file generated with the ITERATOR tool that can be downloaded from www.mathworks.com

Re compile the source with MEX -O prcorr2.c

C = PRCORR2(A,B) computes the correlation between A and B. A and B are arrays witn any number of dims but with same number of elements

Class Support
-------------
A and B can be any numeric type but not complex value. C is a scalar double.

See also CORR2, CORRCOEF, STD2, ITERATOR, MEX

In future I may complement this fast function with a set of them that can replace some slow MATLAB functions.
