shvectortocilm(1)

SHVectorToCilm

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

Usage

call SHVectorToCilm (vector, cilm, lmax, exitstatus)

Parameters

vector : input, real(dp), dimension ( (lmax+1)**2 )
    The input 1-D indexed array of real spherical harmonic coefficients.

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

lmax : input, integer(int32)
    The maximum degree of the output coefficients.

exitstatus : output, optional, integer(int32)
    If present, instead of executing a STOP when an error is encountered, the variable exitstatus will be returned describing the error. 0 = No errors; 1 = Improper dimensions of input array; 2 = Improper bounds for input variable; 3 = Error allocating memory; 4 = File IO error.

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+1.
