✦ Synopsis


Using the theory of s-orthogonality and reinterpreting it in terms of the standard orthogonal polynomials on the real line, we develop a method for constructing Gauss-Turfin-type quadrature formulae. The determination of nodes and weights is very stable. For finding all weights, our method uses an upper triangular system of linear equations for the weights associated with each node. Numerical examples are included.

In this paper, which is connected with the work of Ma, Rokhlin and Wandzura [1], a numerical scheme for the construction of generalized Gauss-Turin quadrature, replacing the polynomials with functions from a rather wide class, is presented. In a special case, this construction reduces itself to the
