Compute forward Wigner transform for a complex signal directly (without using SSHT).
[out] | flmn | Harmonic coefficients. If n_mode is different from SO3_N_MODE_ALL, this array has to be nulled before being passed to the function. |
[in] | f | Function on sphere. Provide a buffer of size (2*L-1)*L*(2*N-1). |
[in] | parameters | A fully populated parameters object. The reality flag is ignored. Use so3_core_forward_via_ssht_real instead for real signals. |
