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
MultiVectorScalarThe type of the entries of the input and output (multi)vectors.
MatrixScalarThe type of the entries of the sparse matrix.
DeviceThe Kokkos Device type; must be a specialization of Kokkos::Device.
