Detailed Description

template<typename T_Real, typename T_Identifier>
struct codi::DuplicateJacobianRemover< T_Real, T_Identifier >

Combines entries of Jacobians with the same identifier.

This class is used in the storing process of the Jacobians for an expression. For each pushData, it checks if a Jacobian with the same identifier has already been pushed. If so, then it combines these Jacobians.

This behavior can be enabled with -DCODI_RemoveDuplicateJacobianArguments=1. See JacobianBaseTape::pushJacobians for details.

Template Parameters

T_Real	The computation type of a tape, usually chosen as ActiveType::Real.
T_Identifier	The adjoint/tangent identifier type of a tape, usually chosen as ActiveType::Identifier.

void codi::DuplicateJacobianRemover< T_Real, T_Identifier >::storeData ( Vec & vec )

inline

Add the data to the provided vector. Resets the internal data for a new statement push.

Template Parameters

Vec	DataInterface with Chunk2<Real, Identifier> as data.
