Expand description

A trait for types that represent matrix-free linear operations

This trait abstracts the concept of a linear operator that maps vectors from one space to another, without explicitly storing a matrix.

Required Methods§

Source

fn apply(&self, x: &ArrayView1<'_, F>) -> LinalgResult<Array1<F>>

Apply the linear operator to a vector

Source

fn nrows(&self) -> usize

Get the number of rows in the linear operator

Source

fn ncols(&self) -> usize

Get the number of columns in the linear operator

Provided Methods§

Source

fn is_symmetric(&self) -> bool

Check if the linear operator is symmetric

Source

fn is_positive_definite(&self) -> bool

Check if the linear operator is positive definite
