A note on Laguerre truncated polynomials and quadrature formula
Abstract
In this contribution we deal with Gaussian quadrature rules based on orthogonal polynomials associated with a weight function w(x)= xα e-x supported on an interval (0,z), z>0. The modified Chebyshev algorithm is used in order to test the accuracy in the computation of the coefficients of the three-term recurrence relation, the zeros and weights, as well as the dependence on the parameter z.
