An Automatic Quadrature Algorithm Based on the Trapezoidal Formula,

Abstract

The formulas that this subroutine (WNEW) is based on are most powerful when the integrand f does not have a singularity (a singularity is a point where df/dx does not exist) in the interior of the range of integration; however, singularities at end-points of intervals are allowed. Indeed, it is in the cases where f has singularities at the end-points of the range of integration that the subroutine WNEW is superior to other subroutines.
