scipy.special.j_roots(n, alpha, beta, mu=False)[source]

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