Struct AmgLevel 

Source 
pub struct AmgLevel {
    pub a: HostCsr,
    pub p: HostCsr,
    pub r: HostCsr,
    pub diag: Vec<f64>,
}
Expand description

A single level of the multigrid hierarchy.

Fields§

§a: HostCsr

The (fine) operator on this level.

§p: HostCsr

The prolongation (interpolation) operator to this level from the next coarser level: fine = P · coarse.

§r: HostCsr

The restriction operator R = Pᵀ.

§diag: Vec<f64>

The diagonal of a, cached for weighted-Jacobi smoothing.
