correl
correlation of two variables
Calling Sequence
rho=correl(x, y [, fre])
Arguments
- x
real or complex vector.
- y
real or complex vector.
- fre
matrix of type length(x) x length(y). (Optional)
Description
correl(x,y)
or correl(x,y, fre)
computes the
correlation of two variables x
and y
.
If you use correl(x,y), x
and y
must be the same
size (size(x, "*") must be equal to size(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 frequencies of x_i&y_j.

Examples
// correl(x, y) x = [2.5 7.5 12.5 17.5]; y = [6.3 7.1 8.2 9.4]; r = correl(x, y) // correl(x, y, fre) h=[0 1 2] fre=[.03 .12 .07;.02 .13 .11;.01 .13 .14;.01 .09 .14] rho=correl(x,h,fre)
