Struct PolarTranslationResidual 

pub struct PolarTranslationResidual {
    orders: Vec<i32>,
    arguments: [Vec<Complex>; 4],
    radial: Radial,
    size: usize,
}

What polar_translation_array saves for its pullback: the orders, the radial kind and the four arguments, each stored once when it is one value for all outputs.

The pullback keeps every output in index order and adds the cotangents of scalar arguments in that order, so its result does not depend on the thread count.

Fields

orders: Vec<i32>

arguments: [Vec<Complex>; 4]

radial: Radial

size: usize

Implementations

impl PolarTranslationResidual

fn element(&self, i: usize) -> (i32, [Complex; 4])

pub fn pushforward(&self, tangents: [&[Complex]; 4]) -> Result<Vec<Complex>>

Directional derivative of the four broadcast polar arguments.

pub fn pullback(&self, cotangent: &[Complex]) -> Result<[Vec<Complex>; 4]>

The gradients of all four continuous arguments; an argument given as one value for all outputs gets the sum of its gradients.

impl PolarTranslationResidual

pub fn new( orders: Vec<i32>, arguments: [Vec<Complex>; 4], radial: Radial, ) -> Result<Self>

Retain broadcast inputs and prepare static labels without evaluating translations.

Trait Implementations

impl Debug for PolarTranslationResidual

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
