orthax.laguerre.lagnorm(n)Source

Norm of nth Laguerre polynomial.

The norm \(\gamma_n\) is defined such that

\(\int_{0}^{\inf} L_n^2(x) \exp(-x) dx = \gamma_n^2\)

With this definition \(\gamma_n^2 = 1\)

Parameters:

n (int) – Order of Laguerre polynomial.

Returns:

gamma_n (float) – Norm of the nth Laguerre polynomial.
