mpmath has it: http://mpmath.googlecode.com/svn/trunk/doc/build/functions/zeta.html#lerch-t... Fredrik

Hi Josef, I was planning to work on something related (polylog), and I started some groundwork : https://github.com/johannct/scipy/tree/polylog But it recently stalled, due to overburden. Also I would like to start with a complete implementation of the zeta function (analytic continuation) as in mpmath..... best, Johann On 11/01/2011 04:28 PM, josef.pktd@gmail.com wrote:
