scipy.special.eval_laguerre

scipy.special.eval_laguerre(n, x, out=None) = <ufunc 'eval_laguerre'>

Evaluate Laguerre polynomial at a point.

The Laguerre polynomials can be defined via the confluent hypergeometric function ${}_1F_1$ as

$$L_n(x) = {}_1F_1(-n, 1, x).$$

When $n$ is an integer the result is a polynomial of degree $n$.

Parameters:

n : array_like

Degree of the polynomial. If not an integer the result is determined via the relation to the confluent hypergeometric function.

x : array_like

Points at which to evaluate the Laguerre polynomial

Returns:

L : ndarray

Values of the Laguerre polynomial
