 Hello scipy developers,

 you may be interested in my code for spherical harmonics.
 Present function sph_harm from scipy.special is vectorized
 and thus slow.

 I took the algorithm for associated legendre polynoms from
 numerical recipies in C, and modified it to include
 normalization.  This way two factorials almost factor out,
 and numbers keep small.

 I hope it will be usefull
