A new method for testing global automatic quadrature programs is introduced. This method, with only one run, gives complete information on the behaviour of the integration program for a single function and any user tolerance, and is wel1 suited to statistic and parametric studies with a large number of integrands. The method is applied to study the behaviour of some well known global automatic quadrature routines (QAG, QAGS, QXG, QXGS).

Abstract
A new method for testing global automatic quadrature programs is introduced. This method, with only one run, gives complete information on the behaviour of the integration program for a single function and any user tolerance, and is wel1 suited to statistic and parametric studies with a large number of integrands. The method is applied to study the behaviour of some well known global automatic quadrature routines (QAG, QAGS, QXG, QXGS).File in questo prodotto:
