# scipy.special.roots_sh_jacobi¶

scipy.special.roots_sh_jacobi(n, p1, q1, mu=False)[source]

Compute the sample points and weights for Gauss-Jacobi (shifted) quadrature. The sample points are the roots of the nth degree shifted Jacobi polynomial, $$G^{p,q}_n(x)$$. These sample points and weights correctly integrate polynomials of degree $$2n - 1$$ or less over the interval $$[0, 1]$$ with weight function $$w(x) = (1 - x)^{p-q} x^{q-1}$$. See 22.2.2 in [AS] for details.

Parameters
nint

p1float

(p1 - q1) must be > -1

q1float

q1 must be > 0

mubool, optional

If True, return the sum of the weights, optional.

Returns
xndarray

Sample points

wndarray

Weights

mufloat

Sum of the weights
