Struct CSRMatrix 

pub struct CSRMatrix {
    pub values: Vec<f32>,
    pub col_indices: Vec<usize>,
    pub row_ptrs: Vec<usize>,
    pub shape: (usize, usize),
}

Compressed Sparse Row (CSR) format for efficient batch operations

Fields

values: Vec<f32>

Non-zero values

col_indices: Vec<usize>

Column indices for each value

row_ptrs: Vec<usize>

Row pointers (start index of each row in values/col_indices)

shape: (usize, usize)

Shape of the matrix (rows, cols)

Implementations

impl CSRMatrix

pub fn from_sparse_vectors( vectors: &[SparseVector], ) -> Result<Self, VectorError>

Create CSR matrix from sparse vectors

pub fn get_row(&self, row: usize) -> Option<SparseVector>

Get a specific row as sparse vector

pub fn multiply_vector( &self, vector: &SparseVector, ) -> Result<Vec<f32>, VectorError>

Matrix-vector multiplication

pub fn memory_usage(&self) -> usize

Get memory usage in bytes

pub fn sparsity(&self) -> f32

Get sparsity of the matrix

Trait Implementations

impl Clone for CSRMatrix

fn clone(&self) -> CSRMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CSRMatrix

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

Formats the value using the given formatter.

impl PartialEq for CSRMatrix

fn eq(&self, other: &CSRMatrix) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
