numpy.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: x : array_like
Values at which the weight function will be computed.
Returns: w : ndarray
The weight function at x.
