corr2

Compute the two-dimensional correlation coefficient between two matrices

Syntax

• r = corr2(A,B)
  

Description

r = corr2(A,B) computes the correlation coefficient between A and B, where A and B are matrices or vectors of the same size.

Class Support

A and B can be numeric or logical. The return value, r, is a scalar double.

Algorithm

corr2 computes the correlation coefficient using

where = mean2(A), and = mean2(B).
