Detailed Description

template<class func_t = funct11>
class o2scl::inte< func_t >

Idea for Future:
It might be useful to have all of the integration classes report the number of function evaluations used in addition to the number of iterations which were taken

Member Function Documentation

◆ get_error()

template<class func_t = funct11>
double o2scl::inte< func_t >::get_error ( )

This will quietly return zero if no integrations have been performed or if the integrator does not estimate the error.

Definition at line 107 of file inte.h.

Member Data Documentation

◆ err_nonconv

template<class func_t = funct11>
bool o2scl::inte< func_t >::err_nonconv

If this is false, the function proceeds normally and may provide convergence information in the integer return value.
