Szegő–Lobatto Quadrature Rules

open access: yesJournal of Computational and Applied Mathematics, 2007
Szegö quadrature rules are analogs of Gauss quadrature rules for the integration of periodic functions. They integrate exactly trigonometric polynomials of as high degree as possible. Szegö quadrature rules have a free parameter, which can be used to prescribe one node.

On the computation of Patterson-type quadrature rules

Journal of Computational and Applied Mathematics, 2022
The Gauss-Kronrod formula is a \((2n+1)\)-point interpolating quadrature formula for \(I[f]=\int_{-1}^1 f(x)d\mu(x)\). It has \(n\) Gauss nodes (zeros of orthogonal polynomial \(p_n\)), and the remaining \(n+1\) nodes are zeros of a the Stieltjes polynomial \(Q_{n+1}\) (orthogonal to \(p_n(x) x^k\), \(k=0,\ldots,n\)) [\textit{D.
