Struct SymbolicSupernodalParams

pub struct SymbolicSupernodalParams<'a> {
    pub relax: Option<&'a [(usize, f64)]>,
}

Tuning parameters for the supernodal factorizations.

Fields

relax: Option<&'a [(usize, f64)]>

Supernode relaxation thresholds.

Let n be the total number of columns in two adjacent supernodes. Let z be the fraction of zero entries in the two supernodes if they are merged (z includes zero entries from prior amalgamations). The two supernodes are merged if:

(n <= relax[0].0 && z < relax[0].1) || (n <= relax[1].0 && z < relax[1].1) || ...
