quadGaussLegendre

Gauss–Legendre quadrature weights and points for numerical integration.

Q = quadGaussLegendre(n), where n is a positive integer, returns the n-point Gauss–Legendre quadrature rule Q as a stucture with fields Q.Points and Q.Weights, which store the n points (in ascending order) and corresponding weights, respectively, of the quadrature rule. An additional field, Q.Properties, stores the degree, type and interval, or domain, of the quadrature rule (the default domain is [-1,1]) in subfields .Degree, .Type and .Domain, respectively.
