#2088: cov() fails for complex input

 The cov() function in lib/function_base.py casts all input to 'float' and
 hence fails on complex inputs. Note that the code already includes the
 appropriate .conj() to handle complex inputs properly [1], so it only
 fails on complex inputs because of the type casting. This should be an
 easy fix.
