Compute the two-dimensional correlation coefficient between two matrices
Syntax
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)
.
