# scipy.special.roots_gegenbauer

`scipy.special.``roots_gegenbauer`(n, alpha, mu=False)

  Gauss-Gegenbauer quadrature.

  Computes the sample points and weights for Gauss-Gegenbauer quadrature. The sample points are the roots of the n-th degree Gegenbauer polynomial, \(C^{\alpha}_n(x)\). These sample points and weights correctly integrate polynomials of degree \(2n - 1\) or less over the interval \([-1, 1]\) with weight function \(f(x) = (1 - x^2)^{\alpha - 1/2}\).

  Parameters: | n : int quadrature order alpha : float alpha must be > -0.5 mu : bool, optional If True, return the sum of the weights, optional.
  Returns: | x : ndarray Sample points w : ndarray Weights mu : float Sum of the weights
