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

New in version 1.7.0.

Examples

>>> from numpy.polynomial.laguerre import lagweight
>>> x = np.array([0, 1, 2])
>>> lagweight(x)
array([1.        , 0.36787944, 0.13533528])
