libtrilinos-ifpack2-dev - 12.18.1-2 main

Ifpack2 provides incomplete factorizations, relaxations, and domain
decomposition operators for linear algebra objects (sparse matrices,
operators, and dense vectors and multivectors) provided by the Tpetra package.
You may use these operators however you wish: for example as preconditioners
in an iterative solver, or as smoothers for algebraic multigrid.
.
This package provides headers.
