Struct CSRMatrix 

pub struct CSRMatrix<T: Clone> {
    pub data: Vec<T>,
    pub indices: Vec<usize>,
    pub indptr: Vec<usize>,
    pub shape: (usize, usize),
}

Compressed Sparse Row (CSR) format for efficient sparse matrix storage

Fields

data: Vec<T>

Non-zero values stored in row-major order

indices: Vec<usize>

Column indices for each non-zero value

indptr: Vec<usize>

Pointers to the start of each row in data/indices

shape: (usize, usize)

Matrix dimensions (rows, cols)

Implementations

impl<T: Clone + Default + PartialEq> CSRMatrix<T>

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

Create a new empty CSR matrix with given dimensions

pub fn from_dense(dense: &ArrayView2<'_, T>) -> Self

where T: Clone + Default + PartialEq + Copy,

Create CSR matrix from dense array

pub fn to_dense(&self) -> Array2<T>

where T: Clone + Default,

pub fn nnz(&self) -> usize

Get the number of non-zero elements

pub fn sparsity(&self) -> f64

pub fn get_row(&self, row: usize) -> Vec<(usize, T)>

Get values for a specific row

pub fn set(&mut self, row: usize, col: usize, value: T)

Set a value at specific row and column
