Struct SparseMatrix 

pub struct SparseMatrix {
    pub shape: (usize, usize),
    pub row_indices: Vec<usize>,
    pub col_indices: Vec<usize>,
    pub values: Vec<f64>,
}

Simple sparse matrix representation in COO (Coordinate) format

Fields

shape: (usize, usize)

Shape of the matrix (rows, cols)

row_indices: Vec<usize>

Row indices of non-zero values

col_indices: Vec<usize>

Column indices of non-zero values

values: Vec<f64>

Non-zero values

Implementations

impl SparseMatrix

pub fn new(shape: (usize, usize)) -> Self

Create a new empty sparse matrix

pub fn push(&mut self, row: usize, col: usize, value: f64)

Add a non-zero value at (row, col)

pub fn to_dense(&self) -> Array2<f64>

Convert to dense Array2

pub fn nnz(&self) -> usize

Get number of non-zero elements
