Struct MatrixBuilder 

pub struct MatrixBuilder { /* private fields */ }

Fluent builder for matrix operations

Implementations

impl MatrixBuilder

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

Create a new matrix builder

pub fn from_data( data: Vec<f32>, rows: usize, cols: usize, ) -> Result<Self, String>

Create from existing data

pub fn identity(size: usize) -> Self

Create an identity matrix

pub fn random(rows: usize, cols: usize, min: f32, max: f32) -> Self

Create a matrix filled with random values

pub fn safe(self) -> Self

Enable safe mode

pub fn set(self, row: usize, col: usize, value: f32) -> Result<Self, String>

Set a value at position (row, col)

pub fn fill(self, value: f32) -> Self

Fill the matrix with a value

pub fn scale(self, factor: f32) -> Self

Scale all elements

pub fn transpose(self) -> Self

Transpose the matrix

Converts an MxN matrix to an NxM matrix by swapping rows and columns. Uses row-major to row-major transposition for cache efficiency.

pub fn multiply(&self, other: &MatrixBuilder) -> Result<MatrixBuilder, String>

Multiply by another matrix

Computes C = A × B where A is self (MxN), B is other (NxP), and C is (MxP). Uses standard O(M×N×P) algorithm with row-major order optimization.

pub fn multiply_vector(&self, vector: &[f32]) -> Result<Vec<f32>, String>

Multiply by a vector

Computes y = A × x where A is self (MxN), x is vector (N), and y is (M). Uses row-major order for cache-efficient access.

pub fn dimensions(&self) -> (usize, usize)

Get matrix dimensions

pub fn build(self) -> (Vec<f32>, usize, usize)

Build the final matrix

pub fn as_slice(&self) -> &[f32]

Get a reference to the underlying data

Trait Implementations

impl Clone for MatrixBuilder

fn clone(&self) -> MatrixBuilder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatrixBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
