In this paper we use the constrained mock-Chebyshev least squares interpolation to obtain stable quadrature formulas with high degree of exactness and accuracy from equispaced nodes. We numerically prove the effectiveness of the proposed algorithm by several examples.

Abstract
In this paper we use the constrained mock-Chebyshev least squares interpolation to obtain stable quadrature formulas with high degree of exactness and accuracy from equispaced nodes. We numerically prove the effectiveness of the proposed algorithm by several examples.File in questo prodotto:
