shcilmtovector(1)

SHCilmToVector

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

Usage

call SHCilmToVector (cilm, vector, lmax, exitstatus)

Parameters

cilm : input, real(dp), dimension (2, lmax+1, lmax+1)
    The input real spherical harmonic coefficients.

vector : output, real(dp), dimension ( (lmax+1)**2 )
    The indexed output real spherical harmonic coefficients.

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

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

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