Description Computes the value of LŠm(r), the associated Laguerre polynomial for mode indices m,a .
Syntax Lval = Lagr( r, m, a )
Parameters Lval (Double) Return value for the associated Laguerre polynomial of mode indices m,a evaluated at coordinate r.
r As Double Argument used to evaluate the polynomial.
m As Double Radial mode index.
a As Double Azimuthal mode index.
Remarks Computes the value of LŠm(x), the associated Laguerre polynomial of mode indices (m,a) at value r.
The associated Laguerre polynomial obeys the recursion relation LŠm(r) = LŠ+1m(r) - LŠ+1m-1(r)
