Design of quadrature rules for Müntz and Müntz-logarithmic polynomials using monomial transformation [PDF]

, 2009
A method for constructing the exact quadratures for Müntz and Müntz-logarithmic polynomials is presented. The algorithm does permit to anticipate the precision (machine precision) of the numerical integration of Müntz-logarithmic polynomials in terms of ...
