scipy.special.eval_legendre

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

Evaluate Legendre polynomial at a point.

The Legendre polynomials can be defined via the Gauss hypergeometric function 2F1 as

Pn(x)=2F1(n,n+1;1;(1x)/2).

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 Gauss hypergeometric function.

x : array_like

Points at which to evaluate the Legendre polynomial

Returns:

P : ndarray

Values of the Legendre polynomial
