CORRCOEF Correlation coefficients.

CORRCOEF(X) is a matrix of correlation coefficients formed

from array X whose each row is an observation, and each

column is a variable.

CORRCOEF(X,Y), where X and Y are column vectors is the same as

CORRCOEF([X Y]).

If C is the covariance matrix, C = COV(X), then CORRCOEF(X) is

the matrix whose (i,j)'th element is

C(i,j)/SQRT(C(i,i)*C(j,j)).

See also COV, STD.
