Enum PenaltyRepresentation 

pub enum PenaltyRepresentation {
    Dense(Array2<f64>),
    Banded {
        bands: Vec<Array1<f64>>,
        offsets: Vec<i32>,
    },
    Kronecker {
        left: Array2<f64>,
        right: Array2<f64>,
    },
}

Variants

Dense(Array2<f64>)

Banded

Fields

bands: Vec<Array1<f64>>

offsets: Vec<i32>

Kronecker

Fields

left: Array2<f64>

Full penalty-block Kronecker product left ⊗ right: each entry of left scales an entire copy of right in the dense expansion.

This is distinct from chunked kernel design assembly, where center rows are kernel-evaluation arguments rather than matrix factors.

right: Array2<f64>

Implementations

impl PenaltyRepresentation

pub fn block_dimension(&self) -> usize

Side length of the square penalty block this representation expands to.

pub fn to_block_dense(&self) -> Array2<f64>

Materialize this representation (Dense / Banded / Kronecker) into a single dense symmetric penalty block.

Trait Implementations

impl Clone for PenaltyRepresentation

fn clone(&self) -> PenaltyRepresentation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
