Publisher review:Fast Clenshaw-Curtis Quadrature computes Clenshaw Curtis weights and nodes using the FFT. This extremely fast and efficient algorithm uses MATLAB's ifft routine to compute the Clenshaw-Curtis nodes and weights in linear time. The routine appears optimal for 2^N 1 points.
Running on an average laptop, this routine computed N=2^20 1 (1048577 points) in about 4.5 seconds. Great for integrating highly oscillatory functions. Requirements: ยท MATLAB Release: R14
