Struct SolveStats 

pub struct SolveStats {
    pub calls: usize,
    pub hyper_calls: usize,
    pub rhs_density_sum: f64,
    pub result_density_sum: f64,
}

Counters of one kind of solve (FTRAN, BTRAN or FTRAN for update), accumulated over the life of the Lu (not reset by a factorization). The contract’s mean densities are the methods SolveStats::mean_rhs_density and SolveStats::mean_result_density over exact sums (no division per call).

Fields

calls: usize

Number of calls.

hyper_calls: usize

Calls served by the hypersparse algorithm (HF or HB).

rhs_density_sum: f64

Sum over the calls of the right-hand side density count/m.

result_density_sum: f64

Sum over the calls of the result density count/m (pattern size: the reach for hypersparse calls, the exact support otherwise).

Implementations

impl SolveStats

pub fn mean_rhs_density(&self) -> f64

Mean right-hand side density (0 without calls).

pub fn mean_result_density(&self) -> f64

Mean result density (0 without calls).

pub fn hyper_fraction(&self) -> f64

Fraction of the calls served by the hypersparse algorithm.
