I've been working on a plane wave expansion in spherical harmonics.. as demonstrated in Bohren and Huffman (if anyone's familiar with it_)... I have more or less finished my code in Matlab and I'm putting in values to expand and compare with the exact solution...(adsbygoogle = window.adsbygoogle || []).push({});

in short, i'm having trouble when defining some of my components as zero... getting results going crazy all over the place.!! now I appreciate this would seem like a problem with the code but looking at the equations in Bohren and Huffman(4.19) (and in my code) there seems to be a different problem!..

one of the terms is divisible by a sin(m*phi) value and of course this value is going to go to zero with my phi and then the term goes to infinity!!! so my result ends up being nonsensical..>

if anyone is familiar with the field t'would be nice to hear!
