Struct GpuCooMatrix

Source

pub struct GpuCooMatrix {
    pub row_idx: Vec<usize>,
    pub col_idx: Vec<usize>,
    pub values: Vec<f64>,
    pub n_rows: usize,
    pub n_cols: usize,
}

Expand description

Sparse matrix in coordinate (COO) format.

Entries can be pushed in arbitrary order; call to_csr or to_csc to produce a compressed representation. Duplicate (row, col) entries are summed during conversion.

Fields§

§row_idx: Vec<usize>

Row indices of non-zero entries.

§col_idx: Vec<usize>

Column indices of non-zero entries.

§values: Vec<f64>

Values of non-zero entries.

§n_rows: usize

Number of rows.

§n_cols: usize

Number of columns.

Implementations§

Source §

impl GpuCooMatrix

Source

pub fn new(n_rows: usize, n_cols: usize) -> Self

Create an empty COO matrix of the given shape.

Source

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

Append a single triplet (row, col, val).

Panics in debug mode when indices are out of bounds.

Source

pub fn from_triplets( n_rows: usize, n_cols: usize, rows: &[usize], cols: &[usize], vals: &[f64], ) -> SparseResult<Self>

Construct a COO matrix from parallel triplet slices.

§Errors

Returns SparseError::InconsistentData when slice lengths differ, or SparseError::IndexOutOfBounds when any index exceeds the declared dimensions.

Source

pub fn to_csr(&self) -> GpuCsrMatrix

Convert to CSR by sorting triplets in row-major order and summing duplicates.

Source

pub fn to_csc(&self) -> GpuCscMatrix

Convert to CSC by sorting triplets in column-major order and summing duplicates.
