Trait optimization::Summation1 [−] [src]

pub trait Summation1: Summation + Function1 {
    fn term_gradient(&self, position: &[f64], term: usize) -> Vec<f64>;

    fn partial_gradient<T: IntoIterator<Item=I>, I: Borrow<usize>>(&self, position: &[f64], terms: T) -> Vec<f64> { ... }
}

Defines a summation of individual functions fᵢ(x), assuming that each function has a first derivative.

Required Methods

fn term_gradient(&self, position: &[f64], term: usize) -> Vec<f64>

Computes the gradient of one individual function identified by term at the given position.

Provided Methods

fn partial_gradient<T: IntoIterator<Item=I>, I: Borrow<usize>>(&self, position: &[f64], terms: T) -> Vec<f64>

Computes the partial gradient over a set of terms at the given position.
