Constructor & Destructor Documentation

◆ TensorSignature() [1/3]

exatn::numerics::TensorSignature::TensorSignature ( std::initializer_list< std::pair< SpaceId, SubspaceId >> subspaces )

Create a tensor signature by specifying pairs <space_id,subspace_id> for each tensor dimension: Case 1: space_id = SOME_SPACE: Then subspace_id refers to the base offset [0..*) in an anonymous abstract space; Case 2: space_id != SOME_SPACE: Then space is registered and subspace_id refers to its registered subspace.

◆ TensorSignature() [2/3]

exatn::numerics::TensorSignature::TensorSignature ( unsigned int rank )

Create a default tensor signature of std::pair<SOME_SPACE,0> by providing the tensor rank only.

◆ TensorSignature() [3/3]

exatn::numerics::TensorSignature::TensorSignature ( )

Create an empty tensor signature.

Member Function Documentation

◆ appendDimension()

void exatn::numerics::TensorSignature::appendDimension ( std::pair< SpaceId, SubspaceId > subspace = {SOME_SPACE,0} )

Appends a new subspace at the end, increasing the signature rank by one.

◆ deleteDimension()

void exatn::numerics::TensorSignature::deleteDimension ( unsigned int dim_id )

Deletes a specific subspace, reducing the signature rank by one.

◆ getDimSpaceId()

SpaceId exatn::numerics::TensorSignature::getDimSpaceId ( unsigned int dim_id ) const

Get the space/subspace id for a specific tensor dimension.

◆ getRank()

unsigned int exatn::numerics::TensorSignature::getRank ( ) const

Get tensor rank (number of dimensions).

◆ isCongruentTo()

bool exatn::numerics::TensorSignature::isCongruentTo ( const TensorSignature & another ) const

Returns TRUE if the tensor signature coincides with another tensor signature.

◆ printIt()

void exatn::numerics::TensorSignature::printIt ( ) const

Print.

◆ resetDimension()

void exatn::numerics::TensorSignature::resetDimension	(	unsigned int	dim_id,
		std::pair< SpaceId, SubspaceId >	subspace
	)

Resets a specific subspace.
