Methods

impl<N: Zero + Clone + Copy> DMat6<N>

fn new_zeros(nrows: usize, ncols: usize) -> DMat6<N>

Builds a matrix filled with zeros.

Arguments

• dim - The dimension of the matrix. A dim-dimensional matrix contains dim * dim components.

fn is_zero(&self) -> bool

Tests if all components of the matrix are zeroes.

fn reset(&mut self)

Set this matrix components to zero.

impl<N: Zero + Copy + Rand> DMat6<N>

fn new_random(nrows: usize, ncols: usize) -> DMat6<N>

Builds a matrix filled with random values.

impl<N: One + Zero + Clone + Copy> DMat6<N>

fn new_ones(nrows: usize, ncols: usize) -> DMat6<N>

Builds a matrix filled with a given constant.

impl<N> DMat6<N>

fn nrows(&self) -> usize

The number of row on the matrix.

fn ncols(&self) -> usize

The number of columns on the matrix.

fn as_vec(&self) -> &[N]

Gets a reference to this matrix data. The returned vector contains the matrix data in column-major order.

fn as_mut_vec(&mut self) -> &mut [N]

Gets a mutable reference to this matrix data. The returned vector contains the matrix data in column-major order.

impl<N: Zero + Clone + Copy> DMat6<N>

fn from_elem(nrows: usize, ncols: usize, elem: N) -> DMat6<N>

Builds a matrix filled with a given constant.

fn from_row_vec(nrows: usize, ncols: usize, vec: &[N]) -> DMat6<N>

Builds a matrix filled with the components provided by a vector. The vector contains the matrix data in row-major order. Note that from_col_vec is a lot faster than from_row_vec since a $dmat stores its data in column-major order.

The vector must have at least nrows * ncols elements.

fn from_col_vec(nrows: usize, ncols: usize, vec: &[N]) -> DMat6<N>

Builds a matrix filled with the components provided by a vector. The vector contains the matrix data in column-major order. Note that from_col_vec is a lot faster than from_row_vec since a $dmat stores its data in column-major order.

The vector must have at least nrows * ncols elements.

fn from_fn<F: FnMut(usize, usize) -> N>(nrows: usize, ncols: usize, f: F) -> DMat6<N>
