SHCindexToCilm
Convert a two-dimensional indexed array of spherical harmonic coefficients to a three-dimensional array.
Usage
cilm = SHCindexToCilm (cindex, [lmax])
Returns
cilm: float, dimension (2,lmax+1,lmax+1)- The input spherical harmonic coefficients.
cilm[0,:,:]andcilm[1,:,:]correspond to either the real and imaginary components, or cosine and sine coefficients, respectively.
Parameters
cindex: float, dimension (2, (lmaxin+1)*(lmaxin+2)/2)- The indexed spherical harmonic coefficients.
lmax: optional, integer, default =lmaxin- The maximum degree of the output coefficients to convert.
Description
SHCindexToCilm will convert a two-dimensional indexed array of spherical harmonic coefficients to a three-dimensional array of complex spherical harmonic coefficients. The degree l and order m corresponds to the index l*(l+1)/2+m.
