Struct IluColoringPreconditioner

Source

pub struct IluColoringPreconditioner<T: ComplexField> { /* private fields */ }

Expand description

Parallel ILU using Graph Coloring / Level Scheduling

This approach analyzes the sparsity pattern of L and U to find independent rows that can be solved in parallel. Rows are grouped into “levels” where all rows in a level depend only on rows from previous levels.

Good for matrices with limited fill-in and structured sparsity patterns.
