covar
covariance of two variables
Calling Sequence
s=covar(x,y,fre)
Arguments
- x
real or complex vector
- y
real or complex vector
- fre
matrix of type length(x) x length(y)
Description
covar(x,y,fre)
computes the covariance of two variables x and y.
fre is a matrix of dimensions length(x) x length(y). In fre the element
of indices (i,j) corresponds to the value or number or frequences of
x_i&y_j.
