Title of program: GAUSSH Catalogue Id: ABBL_v1_0 Nature of problem In the study of physical problems, the need often arises for evaluating definite integrals numerically. The Gaussian quadrature is known as one of the most efficient quadrature schemes. The present program generates the abscissae and weights for the Gauss-Hermite quadrature formulas for integrals of the form integral (-infinity, +infinity) e^-x^2 f(x)dx very rapidly and with high accuracy even in the case of a great many abscissae.
