NAME

lmCalculations

SYNOPSIS

#include ccSHT.h

void lmCalculations(int lmax, flt8 *calc1, flt8 *calc2, flt8 *calc3, flt8 *calc4 );

DESCRIPTION

This function is a member of the ccSHT library which does preliminary calculations used by calculateQlm() to compute the associated Legendre polynomials. These calculations are only functions of l and m. The user must allocate memory for each of these calculations before calling lmCalculations(). The amount of memory required is explained below in the description of the input parameters.

lmax: This is the maximum l value for which the associated Legendre polynomials will be calculated. It is important that this is the same as the lmax which is passed to calculateQlm().
calc1: A vector of length (lmax+1) eight byte floating point numbers.
calc2: A vector of length (lmax+1) eight byte floating point numbers.
calc3: A vector of length ((lmax*lmax + 3*lmax)/2+1) eight byte floating point numbers.
calc4: A vector of length ((lmax*lmax + 3*lmax)/2+1) eight byte floating point numbers.
