— Function File: corrcoef (x, y)

Compute correlation.

If each row of x and y is an observation and each column is a variable, the (i, j)-th entry of corrcoef (x, y) is the correlation between the i-th variable in x and the j-th variable in y.

          corrcoef(x,y) = cov(x,y)/(std(x)*std(y))

If called with one argument, compute corrcoef (x, x).
