numpy.polynomial.laguerre.lagweight¶

numpy.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

New in version 1.7.0.
