Trait representing a shaped matrix whose entries can be accessed at will using their row and column position.

Required Methods

fn rows(&self) -> usize

Return the number of rows of the matrix.

fn cols(&self) -> usize

Return the number of columns of the matrix.

unsafe fn get_unchecked(&self, row: usize, column: usize) -> f32

Get the value of the entry at (row, column) without bounds checking.

unsafe fn get_unchecked_mut(&mut self, row: usize, column: usize) -> &mut f32

Get a mutable reference to the value of the entry at (row, column) without bounds checking.

Provided Methods

fn get(&self, row: usize, column: usize) -> f32

Get the value of the entry at (row, column).

Panics

Will panic if the element accessed is out of bounds.

fn get_mut(&mut self, row: usize, column: usize) -> &mut f32

Get a mutable reference to value of the entry at (row, column).

Panics

Will panic if the element accessed is out of bounds.

fn set(&mut self, row: usize, column: usize, value: f32)

Set the value of the entry at (row, column) to value.

Panics

Will panic if the element accessed is out of bounds.

unsafe fn set_unchecked(&mut self, row: usize, column: usize, value: f32)

Set the value of the entry at (row, column) to value without bounds checking.
