Detailed Description

template<class func_t = funct11, class dfunc_t = func_t>
class o2scl::root_de< func_t, dfunc_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.
