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/92b4b754966e4a581f924d4bfd1b0db7ab47c886.svg)
. The Chebyshev 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.
