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
xarray_like

Values at which the weight function will be computed.

Returns
wndarray

The weight function at x.

Notes
