Struct MatrixView 

pub struct MatrixView<'a> { /* private fields */ }

Immutable row-major matrix view over a slice.

Implementations

impl<'a> MatrixView<'a>

pub fn row_major(data: &'a [f64], rows: usize, cols: usize) -> Result<Self>

Creates a validated row-major matrix view.

pub fn new( data: &'a [f64], rows: usize, cols: usize, layout: MatrixLayout, ) -> Result<Self>

Creates a validated matrix view.

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

Returns the underlying data.

pub fn shape(&self) -> MatrixShape

Returns the matrix shape.

pub fn rows(&self) -> usize

Returns the number of rows.

pub fn cols(&self) -> usize

Returns the number of columns.

pub fn layout(&self) -> MatrixLayout

Returns the matrix layout.

pub fn len(&self) -> usize

Returns the number of matrix elements.

pub fn is_empty(&self) -> bool

Returns whether the matrix has no elements.

pub fn get(&self, row: usize, col: usize) -> Option<f64>

Returns the value at (row, col), or None if out of bounds.

pub fn row(&self, row: usize) -> Option<&'a [f64]>

Returns a contiguous row, or None if out of bounds.
