OK, perhaps I will just continue preevaluating the expressions involving special functions. Thank you for the help Fancesc +1 to Pauli's suggestion. On Sat, Jun 26, 2010 at 6:19 AM, Pauli Virtanen <pav@iki.fi> wrote:

Yeah, you need to explicitly code the support for new functions in numexpr. But another possibility, more doable, would be to code the scipy.special functions by using numexpr as a computing back-end.
Would it be possible to add generic support for user-supplied ufuncs into numexpr? This would maybe be more of a convenience feature than a speed improvement, although perhaps some speed could be gained by evaluating ufuncs per-block.
