Struct Matrix 

pub struct Matrix { /* private fields */ }

A contiguous row-major dense matrix.

Implementations

impl Matrix

pub fn new( rows: usize, cols: usize, data: Vec<f64>, ) -> Result<Self, MatrixError>

Builds a matrix from row-major data.

Errors

Returns MatrixError::DimensionsOverflow if the dimensions overflow, or MatrixError::InvalidShape when the data length is wrong.

pub fn from_rows(rows: Vec<Vec<f64>>) -> Result<Self, MatrixError>

Builds a matrix from nested rows.

Errors

Returns MatrixError::RaggedRows if row lengths differ.

pub fn zeros(rows: usize, cols: usize) -> Self

Returns a zero-filled matrix.

pub const fn rows(&self) -> usize

Number of rows.

pub const fn cols(&self) -> usize

Number of columns.

pub fn as_slice(&self) -> &[f64]

Row-major backing storage.

pub fn as_mut_slice(&mut self) -> &mut [f64]

Mutable row-major backing storage.

pub fn row(&self, row: usize) -> &[f64]

Returns one row.
