Struct FromArrayResidual 

pub struct FromArrayResidual {
    response: DMatrix<Complex>,
    channels: Channels,
    scattered: [DMatrix<Complex>; 2],
}

What from_array saves for its pullback: the response, the channel arrays and the scattered fields.

Fields

response: DMatrix<Complex>

channels: Channels

scattered: [DMatrix<Complex>; 2]

Implementations

impl FromArrayResidual

pub fn state_size(multipoles: usize, modes: usize) -> Result<usize>

Byte count for array radiation state with multipole and plane-wave counts.

impl FromArrayResidual

pub fn shape(&self) -> (usize, usize)

The shape (n, n) of each scattering block, with n plane-wave modes in each direction.

pub fn input_shape(&self) -> (usize, usize)

Multipole and plane-wave mode counts of the channel inputs.

pub fn pushforward( &self, response: &DMatrix<Complex>, channels: &Channels, ) -> Result<Blocks>

Apply response and channel tangents to the recorded scattered fields.

pub fn pullback(&self, cotangent: &Blocks) -> Result<FromArrayGradient>

Effective-response and four-channel cotangents.
