WebC = cov (A,B) returns the covariance between two random variables A and B. If A and B are vectors of observations with equal length, cov (A,B) is the 2 -by- 2 covariance matrix. If A and B are matrices of observations, cov (A,B) treats A and B as vectors and is equivalent to cov (A (:),B (:)). A and B must be the same size. shipt discount code 2021 https://cherylbastowdesign.com
