Gaussian quadrature weights and nodes

Here we present, a number of files/routines to enable the user to easily compute Gaussian quadrature weights and abscissas. You can just open the link and copy-and-paste the text into your system. | ||

1. GQpoints.m---This is a simple MATLAB m-file function
which sets the values of the weights and abscissas for n
= 2, 4, 8, 16, or 32. 2. gaussxw.m---This
is a MATLAB m-file taken from Trefethen's paper, "Is
Gauss quadrature better than Clenshaw-Curtis?" 3. gauss64.dat, gauss128.dat, gauss256.dat, gauss512.dat---These are ASCII text files with the
abscissas and then the weights arranged as a single
vector of length |
