Detailed Description

Linear algebra kernels for small dense matrices and vectors.

This file declares and defines generic computational kernels for small dense linear algebra operations, with matrices and vectors stored as Kokkos::View. The operations are meant as helpers for Tpetra::BlockCrsMatrix.
