Expand description

ELLPACK-format sparse matrix: rows padded to max_nnz_per_row.

Fields§

§n_rows: usize

Number of rows.

§n_cols: usize

Number of columns.

§max_nnz_per_row: usize

Maximum number of non-zeros per row (padding width).

§col_idx: Vec<usize>

Column indices, row-major [n_rows × max_nnz_per_row].

§values: Vec<f64>

Values, row-major [n_rows × max_nnz_per_row].
