◆ appendLeg()

void exatn::numerics::TensorConn::appendLeg	(	std::pair< SpaceId, SubspaceId >	subspace,
		DimExtent	dim_extent,
		TensorLeg	tensor_leg
	)

Appends a new tensor leg as the last leg, increasing the tensor rank by one.

◆ conjugate()

void exatn::numerics::TensorConn::conjugate ( )

Conjugates the connected tensor, which includes complex conjugation of the tensor itself as well as tensor leg direction reversal.

◆ deleteLeg()

void exatn::numerics::TensorConn::deleteLeg ( unsigned int leg_id )

Deletes an existing tensor leg, reducing the tensor rank by one.

◆ deleteLegs()

void exatn::numerics::TensorConn::deleteLegs ( std::vector< unsigned int > & leg_ids )

Deletes a set of existing tensor legs, reducing the tensor rank.

◆ getDimExtent()

DimExtent exatn::numerics::TensorConn::getDimExtent ( unsigned int dim_id ) const

Returns the dimension extent of a specific tensor leg.

◆ getDimSpaceAttr()

std::pair< SpaceId, SubspaceId > exatn::numerics::TensorConn::getDimSpaceAttr ( unsigned int dim_id ) const

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

◆ getNumLegs()

unsigned int exatn::numerics::TensorConn::getNumLegs ( ) const

Returns the total number of legs (tensor rank/order).

◆ getTensor()

std::shared_ptr< Tensor > exatn::numerics::TensorConn::getTensor ( )

Returns a co-owned pointer to the tensor.

◆ getTensorId()

unsigned int exatn::numerics::TensorConn::getTensorId ( ) const

Returns the tensor id.

◆ getTensorLeg()

const TensorLeg & exatn::numerics::TensorConn::getTensorLeg ( unsigned int leg_id ) const

Returns a specific tensor leg.

◆ getTensorLegs()

const std::vector< TensorLeg > & exatn::numerics::TensorConn::getTensorLegs ( ) const

Returns all tensor legs.

◆ isComplexConjugated()

bool exatn::numerics::TensorConn::isComplexConjugated ( ) const

Returns the complex conjugation status of the tensor.

◆ printIt()

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

Prints.

◆ resetLeg()

void exatn::numerics::TensorConn::resetLeg	(	unsigned int	leg_id,
		TensorLeg	tensor_leg
	)

Resets an existing tensor leg (specific connection to another tensor).
