WebNOVELINKOVA: COMPARISON OF CLENSHAW-CURTIS AND GAUSS QUADRATURE Clenshaw-Curtis scheme There are two ways how to describe the idea behind the … 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.
