Detailed Description

template<class func_t = funct, class fp_t = double, const fp_t x5 = inte_gauss56_cern_x5_double, const fp_t w5 = inte_gauss56_cern_w5_double, const fp_t x6 = inte_gauss56_cern_x6_double, const fp_t w6 = inte_gauss56_cern_w6_double>
class o2scl::inte_gauss56_cern< func_t, fp_t, x5, w5, x6, w6 >

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

Note

Currently O2scl supports only types double and long double for the floating point type fp_t .
