Compute the index of an array corresponding to degree l and angular order m.
Usage
index = PlmIndex (l, m)
Parameters
index: function output, integer(int32)- Index of an array of associated Legendre functions corresponding to degree
land angular orderm. l: input, integer(int32)- The spherical harmonic degree.
m: input, integer(int32)- The angular order.
Description
PlmIndex will calculate the index of an array of associated Legendre functions corresponding to degree l and angular order m. The input arrays are generated by routines such as PlmBar, PlmBar_d1, PlmSchmidt, PlmSchmidt_d1, PlmON, PlmON_d1, PLegendreA, and PLegendreA_d1. The array index is equal to l*(l+1)/2+m+1.
