WebClenshaw–Curtis is straightforward to implement in () time by FFT-based methods. Newton–Cotes quadrature is based on approximating f by a polynomial interpolant at equally-spaced points in [−1, 1] , and like Clenshaw–Curtis also integrates polynomials of degree up to n exactly when given n samples. WebThe spectral accuracy of the Gauss-Legendre and Clenshaw-Curtis methods can be traced to the fact that they employ global polynomial interpolation and cluster their abscissas at …

WebClenshaw-Curtis quadrature is a particularly important automatic quadrature scheme for a variety of reasons, especially the high accuracy obtained from relatively few integrand values. However, it has received little use because it requires the computation of a cosine transformation, and the arithmetic cost of this has been prohibitive. WebApr 21, 2024 · The quadrature rule. The particular quadrature rule may be considered to be an "open rule" in that, like Gauss-Legendre quadrature, it doesn't use the endpoints. … asim magdeburg

WebTo get stable and fast algorithms, Domínguez, et al. (), and Xiang, et al. (), proposed the Clenshaw-Curtis-Filon-type method, respectively, which enjoyed extensive applications at present. Although Filon’s methodology leads to many efficient algorithms, most of them suffer to complicate computation of moment integrals. An alternative way to ...
