5,6-point Gaussian quadrature (CERNLIB) More...
#include <inte_gauss56_cern.h>
If is the 5-point approximation, and
is the 6-point approximation to the integral, then integ_err() returns the result
with uncertainty
.
This class is based on the CERNLIB routines RGS56P and DGS56P which are documented at http://wwwasdoc.web.cern.ch/wwwasdoc/shortwrupsdir/d106/top.html
