Struct extendr_api::prelude::sparse::linalg::SupernodalThreshold

pub struct SupernodalThreshold(pub f64);
Expand description

Nonnegative threshold controlling when the supernodal factorization is used.

Increasing it makes it more likely for the simplicial factorization to be used, while decreasing it makes it more likely for the supernodal factorization to be used.

A value of 1.0 is the default.
