DifferentiableFunction

Differentiable Double-valued function suitable for line-search algorithms. The domain of the function is some vectorspace V, and the corresponding gradient is also from V.

Linear Supertypes

(V) ⇒ Double, AnyRef, Any

Abstract Value Members

abstract def apply(x: V): Double

Returns the function value f(x) together with the gradient (grad f)(x)
Returns the function value f(x) together with the gradient (grad f)(x)
