Detailed Description

Header file for generalized spherical harmonic basis.

The complex generalized spherical harmonic coefficients for real data.

For real data, there is the guarantee that C[l,-m,-n] = (-1)^{(m+n)} C[l,m,n]*. So, we only store the upper triangular values for m and n, such that n>=m. These values are then flattened in row major order.
