}

Aggregate statistics from multifrontal factorization.

Reports pivot counts, delay events, and front sizes across all supernodes.

Fields

total_1x1_pivots: usize

Total 1x1 pivots across all supernodes.

total_2x2_pivots: usize

Total 2x2 pivot pairs across all supernodes.

total_delayed: usize

Total delay events across all supernodes.

zero_pivots: usize

Columns that could not be eliminated at root supernodes (zero pivots). These represent rank deficiency in the matrix. A nonzero value means the matrix is numerically singular (or nearly so) — the solve phase must handle this appropriately.

max_front_size: usize

Largest frontal matrix dimension encountered.

supernodes_before_amalgamation: usize

Number of supernodes before amalgamation.

supernodes_after_amalgamation: usize

Number of supernodes after amalgamation.

merges_performed: usize

Number of merge operations performed during amalgamation.

small_leaf_subtrees: usize

Number of small-leaf subtrees identified by classification.

small_leaf_nodes: usize

Number of supernodes processed via the small-leaf fast path.
