Class gradient (o2scl)

O2scl : Class List

template<class func_t, class vec_t = boost::numeric::ublas::vector<double>>
class gradient

Class for automatically computing gradients [abstract base].

Default template arguments

• func_t - (no default)

• vec_t - boost::numeric::ublas::vector < double >

  Idea for Future:

  Consider making an exact_grad class for computing exact gradients.
