Inheritance diagram for o2scl::inte_gauss56_cern< func_t, fp_t, weights_t >:
Detailed Description
template<class func_t = funct, class fp_t = double, class weights_t = inte_gauss56_coeffs_double>
class o2scl::inte_gauss56_cern< func_t, fp_t, weights_t >
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
