Implementations§

Source§

impl AmgTransferOperators

Source

pub fn from_prolongation_adjoint(prolongation: CsrMatrix<S>) -> Self

Build transfer operators with the canonical AMG restriction R = P^H.

AMG setup derives its restriction from the prolongation in scalar-generic Galerkin paths. This constructor makes that contract explicit for callers that only need to provide a custom prolongation.
