Clebsch-Gordan-Coefficients

A Matlab code for computing Clebsch-Gordan Coefficients These are a few scripts which compute the Clebsch-Gordan Coefficeints by using a new recursion method: the sign-exponent recursion. The method uses the iteration of sign and exponent to avoid numerical overflows or underflows. This method is more stable and efficeint than most of methods that I know of so far. For more detailed information, please see a paper to be submitted to Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT): Improving the recursion computation of Clebsch-Gordan coefficients for light scattering simulations.
