chaospy.quadrature.kronrod_jacobi(order, coeffs)[source]

Create the three-terms-recursion coefficients resulting from the Kronrod-Jacobi matrix.

Augment three terms recurrence coefficients to add extra Gauss-Kronrod terms.

Args:
order (int):

Order of the Gaussian quadrature rule.

coeffs (numpy.ndarray):

Three terms recurrence coefficients of the Gaussian quadrature rule.

Returns:

Three terms recurrence coefficients of the Gauss-Kronrod quadrature rule.
