Struct NestedDissectionOrdering 

Source 
pub struct NestedDissectionOrdering;
Expand description

Nested dissection ordering algorithm.

Recursively finds vertex separators to split the graph, orders each partition recursively, then places separator vertices last. This produces a fill-reducing ordering for sparse Cholesky/LU factorization.

Implementations§

Source§

impl NestedDissectionOrdering

Source
