numpy.polynomial.chebyshev.chebweight¶
- numpy.polynomial.chebyshev.chebweight(x)[source]¶
The weight function of the Chebyshev polynomials.
The weight function is
and the interval of
integration is ![[-1, 1]](../../_images/math/5c3818b9565a33fd3aadba10026d32c5e3eea90f.png)
. The Chebyshev 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.
