c = covarmx(x, y, option)
Legacy Name: cov
Computes the covariance matrix of the input elements. c = covarmx(x, y) and c = covarmx(x, y, 1) are equivalent to covarmx([x(:), y(:)]).
Name  Description  

x  Specifies a real or complex matrix. Each column of x represents one vector of observed samples from one variable. Each row of x represents an observation from each variable. If x has only one row, LabVIEW returns a zero matrix.  
y  Specifies a real or complex matrix of the same size as x.  
option  Specifies whether to normalize x by n or n1, where n is the length of x when x is a vector or the number of the rows in x when x is a matrix. option is an integer that accepts the following values.

Name  Description 

c  Returns the covariance matrix. If you specify c = covarmx(x, y) or c = covarmx(x, y, 1), c returns a 2by2 matrix. 
The following table lists the support characteristics of this function.
