Struct SparseIntegerMatrix

Source 
pub struct SparseIntegerMatrix {
    pub rows: Vec<usize>,
    pub cols: Vec<usize>,
    pub vals: Vec<i64>,
    pub shape: (usize, usize),
}
Expand description

Sparse representation of an integer matrix.

Stores only non-zero elements using coordinate format (COO):

  • rows\[i\], cols\[i\], vals\[i\] represent a non-zero element at position (rows[i], cols[i]) with value vals[i]

Fields§

§rows: Vec<usize>

Row indices of non-zero elements

§cols: Vec<usize>

Column indices of non-zero elements

§vals: Vec<i64>

Values of non-zero elements

§shape: (usize, usize)

Matrix dimensions: (number_of_rows, number_of_columns)

Implementations§

Source§

impl SparseIntegerMatrix

Source

pub fn new() -> SparseIntegerMatrix

Creates a new empty sparse integer matrix.

§Returns

A new SparseIntegerMatrix with no entries and shape (0, 0)
