numpy.polynomial.chebyshev.chebweight¶
- polynomial.chebyshev.chebweight(x)[source]¶
The weight function of the Chebyshev polynomials.
The weight function is \(1/\sqrt{1 - x^2}\) and the interval of integration is \([-1, 1]\). 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.
