Module peroxide::structure::hyper_dual

Hyper dual number system for Automatic differentiation

Hyper dual number system

• HyperDual is structure for 2nd order AD

  • value(&self) -> f64
  • slope(&self) -> f64
  • accel(&self) -> f64

• There are two constructors

  • HyperDual::new(T, T, T)
  • hyper_dual(T, T, T)

  extern crate peroxide;
  use peroxide::*;
  
  fn main() {
      let x = hyper_dual(1, 1, 0); // x at x = 1
      (x.clone() + x.clone()).print(); // hyper_dual(2, 2, 0)
      (x.clone() * x.clone()).print(); // hyper_dual(1, 2, 2)
      // and etc.
  }

  • Also, after 0.10.1, you can use reference ops.

  extern crate peroxide;
  use peroxide::*;
  
  fn main() {
      let x = hyper_dual(1,1,0);
      (&x + &x).print();
      (&x * &x).print();
      // and etc.
  }
