numpy.polynomial.chebyshev.chebgauss(deg)
[source]
Gauss-Chebyshev quadrature.
Computes the sample points and weights for Gauss-Chebyshev quadrature. These sample points and weights will correctly integrate polynomials of degree or less over the interval with the weight function .

New in version 1.7.0.
The results have only been tested up to degree 100, higher degrees may be problematic. For Gauss-Chebyshev there are closed form solutions for the sample points and weights. If n = deg
