scipy.stats.corrcoef

scipy.stats.corrcoef(x, y=None, rowvar=False, bias=True)

The correlation coefficients formed from 2-d array x, where the rows are the observations, and the columns are variables.

corrcoef(x,y) where x and y are 1d arrays is the same as corrcoef(transpose([x,y]))

If rowvar is True, then each row is a variables with observations in the columns.
