Hi Graeme,
I can clean this up, the monster is an overkill. Can we chat offline
tomorrow / Monday?

Hi Folks
Digging around some more found the test for the Zernike stuff, now have
from __future__ import division
def tst_nss_spherical_harmonics(): from scitbx import math from scitbx.array_family import flex N=50 M=20 lfg = math.log_factorial_generator(N) nsssphe = math.nss_spherical_harmonics(M+5,50000,lfg)
l = 2 m = 1 t = 1 p = 1
print nsssphe.spherical_harmonic(2, 1, 1, 1)
tst_nss_spherical_harmonics()
Not clear what a log factorial generator is, but seems to work
if I am only caring about small integer l for Ylm do I need to have the big numbers above?
Thanks Graeme

Hi Folks,
Looked and something is used from boost but they don’t appear to be clearly wrapped to Python.
in
scitbx.math.nss_spherical_harmonics
found nearly what I was looking for but it seems to be for some other purpose & not really do what I want (and needs mystery things in constructor….)
_sh = sh(2, 1) Traceback (most recent call last): File "<stdin>", line 1, in <module> Boost.Python.ArgumentError: Python argument types in nss_spherical_harmonics.__init__(nss_spherical_harmonics, int, int) did not match C++ signature: __init__(_object*, int l_max, int mangle, scitbx::math::zernike::log_factorial_generator<double> lgf)
Any clues would be welcome, else wise most sensible thing seems to be to wrap up to Python the boost spherical harmonic code…
Thanks Graeme
