SHVectorToCilm

Convert a 1-dimensional indexed vector of real spherical harmonic coefficients to a three-dimensional array.

Usage

cilm = SHVectorToCilm (vector, [lmax])

Returns

cilm : float, dimension (2, lmax+1, lmax+1)
The 3-D arrary of output real spherical harmonic coefficients.

Parameters

vector : float, dimension ( (lmaxin+1)**2 )
The input 1-D indexed array of real spherical harmonic coefficients.
lmax : optional, optional, default = lmaxin
The maximum degree of the output coefficients.

Description

SHVectorToCilm will convert a 1-dimensional indexed vector of real spherical harmonic coefficients to a three-dimensional array. The degree l, order m, and i (1 = cosine, 2 = sine) corresponds to the index `l**2+(i-1)*l+m.
