`shrinkage::MatrixDesign`

Shrinkage for Rust · rust · 0.3.0

Source: src/problem/runtime.rs

pub struct MatrixDesign<'a, M: ?Sized, V = Vec<f64>>

A borrowed concrete LazyMatrix backend for runtime proximal composition.

V is the native vector accepted by the backend's products. This adapter retains static column access and never depends on a datafit or penalty type.

Inherent implementation

Source: src/problem/runtime.rs

impl<'a, M: ?Sized, V> MatrixDesign<'a, M, V>

`new`

Source: src/problem/runtime.rs

pub fn new(matrix: &'a M) -> Self

Borrow a backend; validation and normalization occur during fitting.
