LaguerreL[n, x] gives the Laguerre polynomial .
LaguerreL[n, a, x] gives the generalized Laguerre polynomial .
Mathematical function (see Section A.3.10).
Explicit polynomials are given when possible.
The Laguerre polynomials are orthogonal with weight function .
They satisfy the differential equation .
LaguerreL[n, x] is an entire function of x with no branch cut discontinuities.
