clenshaw_curtis_rule, a MATLAB code which defines a Clenshaw Curtis quadrature rule.
quadrature_least_squares, a MATLAB code which computes weights for "sub-interpolatory" quadrature rules, that is, it estimates integrals by integrating a polynomial that approximates the function data in a least squares sense.
quadrature_weights_vandermonde, a MATLAB code which determines the weights of a quadrature rule using the Vandermonde matrix.
quadrule, a MATLAB code which defines quadrature rules for 1-dimensional domains.
