Detailed Description

template<Dimension dimEmbedded, Dimension dimAmbient, typename TLinearAlgebraBackend, typename TInteger = DGtal::int32_t>
class DGtal::DiscreteExteriorCalculus< dimEmbedded, dimAmbient, TLinearAlgebraBackend, TInteger >

Aim: DiscreteExteriorCalculus represents a calculus in the dec package. This is the main structure in the dec package. This is used to describe the space on which the dec is build and to compute various operators. Once operators or kforms are created, this structure should not be modified.

Description of template class 'DiscreteExteriorCalculus'

Template Parameters

dimEmbedded	dimension of emmbedded manifold.
dimAmbient	dimension of ambient manifold.
TLinearAlgebraBackend	linear algebra backend used (i.e. EigenSparseLinearAlgebraBackend).
TInteger	integer type forwarded to khalimsky space.

Examples:: dec/exampleDECSurface.cpp, dec/exampleDiscreteExteriorCalculusChladni.cpp, dec/exampleDiscreteExteriorCalculusSolve.cpp, dec/exampleDiscreteExteriorCalculusUsage.cpp, and dec/examplePropagation.cpp.
