Struct RandomMatrix 

pub struct RandomMatrix { /* private fields */ }

A random matrix stored as a flat vector.

Provides basic accessors for the matrix dimensions and elements. The data is stored as a contiguous Vec<f64> in the specified layout.

Implementations

impl RandomMatrix

pub fn new( rows: usize, cols: usize, data: Vec<f64>, layout: MatrixLayout, ) -> RandResult<Self>

Creates a new RandomMatrix from existing data.

Errors

Returns RandError::InvalidSize if data.len() != rows * cols.

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

Creates a zero-filled matrix.

pub fn identity(n: usize, layout: MatrixLayout) -> RandResult<Self>

Creates an identity matrix (must be square).

Errors

Returns RandError::InvalidSize if n == 0.

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 data(&self) -> &[f64]

Returns a reference to the underlying data.

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

Returns a mutable reference to the underlying data.

pub fn into_data(self) -> Vec<f64>

Consumes the matrix and returns the underlying data.

pub fn get(&self, i: usize, j: usize) -> f64

Returns the element at position (i, j).

Panics

Panics if i >= rows or j >= cols.

pub fn set(&mut self, i: usize, j: usize, value: f64)

Sets the element at position (i, j).

Panics

Panics if i >= rows or j >= cols.

pub fn is_square(&self) -> bool

Returns true if the matrix is square.

pub fn frobenius_norm(&self) -> f64

Computes the Frobenius norm of the matrix.

pub fn transpose(&self) -> Self

Returns the transpose of this matrix.
