Expand description

Block-CSR matrix where every stored entry is a block_size × block_size dense tile.

Fields§

§block_size: usize§n_block_rows: usize§n_block_cols: usize§row_ptr: Vec<usize>

Block row start indices, length n_block_rows + 1.

§col_idx: Vec<usize>

Column (block) indices.

§blocks: Vec<Vec<f64>>

Dense tiles, each of length block_size * block_size.

Implementations§

Source §

impl BlockCsrMatrix

Source

pub fn spmv_block(&self, x: &[f64]) -> Vec<f64>

Sparse matrix–vector product treating the matrix as (n_block_rows * block_size) × (n_block_cols * block_size).

Source

pub fn to_csr(&self) -> CsrMatrix

Convert to a flat CsrMatrix.
