Convert a two-dimensional indexed array of spherical harmonic coefficients to a three-dimensional array.
Usage
call SHCindexToCilm (cindex, cilm, degmax, exitstatus)
Parameters
cindex: input, real(dp), dimension (2, (lmaxin+1)*(lmaxin+2)/2)- The indexed spherical harmonic coefficients.
cilm: output, real(dp), dimension (2,degmax+1,degmax+1)- The input spherical harmonic coefficients.
cilm(1,:,:)andcilm(2,:,:)correspond to either the real and imaginary components, or cosine and sine coefficients, respectively. degmax: input, optional, integer(int32), default =lmaxin- 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
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+1. The default is to convert the entire array cindex, but a subset of this array can be converted by specifying the optional argument degmax.
