#1600: Zeta function definition is wrong
---------------------------+------------------------------------------------
Reporter: ignitionweb | Owner: pv
Type: defect | Status: new
Priority: high | Milestone: Unscheduled
Component: scipy.special | Version:
Keywords: zeta |
---------------------------+------------------------------------------------
In scipy.special.zeta it is wrongly defined as sum((k+q)**(-x),k=0..inf)
It should in fact start the sum with k=1 hence sum((k+q)**(-x),k=1..inf)
This causes the function to report back maximum double value instead of
the correct result. see http://stackoverflow.com/q/9354343/697081 for
observational analysis.
