Compute correlation coefficient over all dimensions.

prcorr2.m

% PRCORR2 - Compute correlation coefficient over all dimentions
%
% This is a 10 time faster implementation of MATLABs 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.
