Detailed Description

template<class MultiVectorScalar, class MatrixScalar, class Device>
class Tpetra::LocalCrsMatrixOperator< MultiVectorScalar, MatrixScalar, Device >

Abstract interface for local operators (e.g., matrices and preconditioners).

Template Parameters

MultiVectorScalar	The type of the entries of the input and output (multi)vectors.
MatrixScalar	The type of the entries of the sparse matrix.
Device	The Kokkos Device type; must be a specialization of Kokkos::Device.

	)		const

Same behavior as apply() above, except give KokkosKernels a hint to use an SPMV algorithm that can efficiently handle matrices with imbalanced rows.
