Detailed Description

template<class param_t, class func_t>
class cern_gauss56< param_t, func_t >

5,6-point Gaussian quadrature (CERNLIB)

If $ I_5 $ is the 5-point approximation, and $ I_6 $ is the 6-point approximation to the integral, then integ_err() returns the result $ \frac{1}{2}(I_5+I_6) $ with uncertainty $ |I_5-I_6| $.

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
