numpy.polynomial.laguerre.lagweight

polynomial.laguerre. lagweight ( x ) [source]

Weight function of the Laguerre polynomials.

The weight function is \(exp(-x)\) and the interval of integration is \([0, \inf]\). The Laguerre polynomials are orthogonal, but not normalized, with respect to this weight function.

Parameters

x array_like

Values at which the weight function will be computed.

Returns

w ndarray

The weight function at x.

Notes

New in version 1.7.0.
