X As  Double,
Optional Info As  Long 
)

Associated Laguerre polynomial Lnm(x) (Subroutine version)

Purpose
Computes the associated Laguerre polynomial of x.
Lnm(x) = (-1)^m dm/dxm Ln+m(x)
Parameters
[out]RetAssociated Laguerre polynomial Lnm(x).
[in]NArgument n. (0 <= N < 128)
[in]MArgument m. (0 <= M < 128)
[in]XArgument x.
[out]Info(Optional)
= 0: Successful exit.
= -1: The argument N had an illegal value. (N < 0, N >= 128)
= -2: The argument M had an illegal value. (M < 0, M >= 128)
