Expand description

ELLPACK-format sparse matrix: rows padded to max_nnz_per_row.

Fields§

§n_rows: usize§n_cols: usize§max_nnz_per_row: usize§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].

Implementations§
