Classes
class	terra::linalg::detail::DummyOperator< SrcVectorT, DstVectorT >
	Dummy operator for testing concepts. Implements apply_impl as a no-op. More...
class	terra::linalg::detail::DummyConcreteOperator
	Dummy concrete operator for concept checks. Uses DummyVector as vector types. More...
class	terra::linalg::detail::DummyConcreteBlock2x2Operator
	Dummy block 2x2 operator for concept checks. Contains four DummyConcreteOperator blocks. More...

Namespaces
namespace	terra
namespace	terra::linalg
	Contains linear algebra utilities and functions for the Terra project.
namespace	terra::linalg::detail

Concepts
concept	terra::linalg::OperatorLike
	Concept for types that behave like linear operators.
concept	terra::linalg::GCACapable
	Concept for types that can be used as Galerkin coarse-grid operators in a multigrid hierarchy. See galerkin_coarsening_linear.hpp for more information on GCA.
concept	terra::linalg::Block2x2OperatorLike
	Concept for types that behave like block 2x2 operators. Extends OperatorLike and requires block types and accessors.

Typedefs
template<OperatorLike Operator>
using	terra::linalg::SrcOf = Operator::SrcVectorType
	Alias for the source vector type of an operator.
template<OperatorLike Operator>
using	terra::linalg::DstOf = Operator::DstVectorType
	Alias for the destination vector type of an operator.

Enumerations
enum class	terra::linalg::OperatorApplyMode { terra::linalg::Replace , terra::linalg::Add }
	Modes for applying an operator to a vector. More...
enum class	terra::linalg::OperatorCommunicationMode { terra::linalg::SkipCommunication , terra::linalg::CommunicateAdditively }
	Modes for communication during operator application. More...
enum class	terra::linalg::OperatorStoredMatrixMode { terra::linalg::Off , terra::linalg::Full , terra::linalg::Selective }
	Modes for applying stored matrices. More...

Functions
template<OperatorLike Operator>
void	terra::linalg::apply (Operator &A, const SrcOf< Operator > &src, DstOf< Operator > &dst)
	Apply an operator to a source vector and write to a destination vector.
