### Description

related to ticket:335 (r1122)

Only way I can understand this is that one of my vectors is constant, i.e. zero variance. However zero variance implies, in theory, zero covariance. So I guess we are dealing with numerics here which means we have epsilon/zero which indeed should be inf.
