A note on Laguerre truncated polynomials and quadrature formula

In this contribution we deal with Gaussian quadrature rules based on orthogonal polynomials associated with a weight function $w(x)=x^{\alpha }{e}^{-x}$ 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 $z\mathrm{.}$
