program ssht_test

(

)

Applies SSHT algorithms to perform inverse and forward spherical harmonic transforms (respectively) to check that the original signal is reconstructed exactly (to numerical precision). Test is performed on a random signal with harmonic coefficients uniformly sampled from (-1,1).

Usage: ssht_test B spin, e.g. ssht_test 64 2
