}

A borrowed immutable view of a dense matrix, supporting read-only arithmetic operations.

This trait represents a temporary immutable reference to a matrix’s data, allowing read-only operations like addition, subtraction, scalar multiplication, and matrix-vector multiplication. Matrix views can be created via the columns() methods on a DenseMatrix.

Required Methods

fn into_owned(self) -> Self::Owned

Convert this view into an owned matrix, cloning the data if necessary.

fn gemv_v( &self, alpha: Self::T, x: &<Self::V as Vector>::View<'_>, beta: Self::T, y: &mut Self::V, )

Perform a matrix-vector multiplication with a vector view: y = alpha * self * x + beta * y

fn gemv_o(&self, alpha: Self::T, x: &Self::V, beta: Self::T, y: &mut Self::V)

Perform a matrix-vector multiplication with an owned vector: y = alpha * self * x + beta * y

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
