# 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 $${}_2F_1$$ as

$P_n(x) = {}_2F_1(-n, n + 1; 1; (1 - x)/2).$

When $$n$$ is an integer the result is a polynomial of degree $$n$$. See 22.5.49 in [AS] for details.

Parameters
narray_like

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

xarray_like

Points at which to evaluate the Legendre polynomial

Returns
Pndarray

Values of the Legendre polynomial

roots_legendre

roots and quadrature weights of Legendre polynomials

legendre

Legendre polynomial object

hyp2f1

Gauss hypergeometric function

numpy.polynomial.legendre.Legendre
