Struct Gradients 

pub struct Gradients<T> { /* private fields */ }

The gradients computed by Var::backward.

Query individual gradients using get.

Example

use autodiff::Tape;

let tape = Tape::new();
let x = tape.var(3.0);
let y = tape.var(4.0);
let z = x.clone() * y.clone();  // z = x * y

let grads = z.backward();
assert_eq!(grads.get(&x), 4.0);  // dz/dx = y
assert_eq!(grads.get(&y), 3.0);  // dz/dy = x

Implementations

impl<T: Copy> Gradients<T>

pub fn get(&self, var: &Var<T>) -> T

Returns the gradient with respect to the given variable.
