Inheritance diagram for o2scl::root_de< func_t, dfunc_t, fp_t >:
Detailed Description
template<class func_t = funct, class dfunc_t = func_t, class fp_t = double>
class o2scl::root_de< func_t, dfunc_t, fp_t >
- Note
- At the moment, the functions solve() and solve_bkt() are not implemented for derivative solvers.
- Idea for Future:
- Implement the functions solve() and solve_bkt() for derivative solvers.
