MATLAB scripts are provided for generating to any given accuracy n-point Gauss quadrature rules, n ≥ 1, relative to Jacobi weight functions as well as approximations for the quadrature weights and respective errors. For selected values of the Jacobi parameters, approximations and respective errors are also provided for the associated Christoffel function.
