Detailed Description

Applies SO3 algorithms to perform inverse and forward Wigner 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), using a variety of options.

Usage: so3_test [L [N [L0 [seed]]]]

e.g.
so3_test 64 4 32 314

Defaults: L = 16, N = L, L0 = 0, seed = 1
