The Gaussian quadrature method is an approximate method of calculation of a certain integral . By replacing the variables x = (b - a)t/2 + (a + b)t/2, f(t) = (b - a)y(x)/2 the desired integral is reduced to the form . The Gaussian quadrature formula is. TESTFACT is one of the programs that uses Gauss – Hermite quadrature , but the program is developed for performing factor analysis of dichotomously scored items. In such an analysis, 50 seems to be the maximum number of quadrature points. Note that item discrimination in TESTFACT is expressed on the normal metric.

Applies the 3—point Gaussian quadrature to evaluate the integral I for values of N from 1 to 40 in increments of 1, where the part of the code for solving equation (3) is vectorised (scalar-based calculations replaced with matrix—based calculations).

Matlab Codes (66) MIMO systems (9) Nyquist (13) OFDM (7) Phased Array Antenna (4. They both look decent, though guassquad is purely a gauss-legendre code, gaussg a more general code for standard weight functions, though it is a guass-kronrod scheme. In fact, even my sympoly toolbox provides gaussian quadrature rules, thus the weights and nodes for any standard weight function class.
