public class InfinityMidPointMatrixQuadrature
extends MidPointMatrixQuadrature

This is an exact replacement for MidPointQuadrature i.e., returns the nth stage of refinement of the integral of a function from "a" to "b", except that the function is evaluated at evenly spaced points in 1=x rather than in "x". This allows the upper limit "b" to be as large and positive as the computer allows, or the lower limit "a" to be as large and negative, but not both. "a" and "b" must have the same sign.
