Detailed Description

template<class F>
class concepts::TMatrixBlock< F >

TMatrixBlock are special Tmatrices in block diagonal structure, builded with two Tmatrices itsself.

The columns of the matrix are TColumn.

If a Tmatrix T0 or T1 is not to be added, i.e. its corresponding weight is zero, the TMatrixBlock coincides with the other input Tmatrix or is empty.

Constructor & Destructor Documentation

◆ TMatrixBlock()

template<class F >

concepts::TMatrixBlock< F >::TMatrixBlock	(	const TMatrix< F > *	T0,
		F	weight0 = `1.0`,
		const TMatrix< F > *	T1 = `0`,
		F	weight1 = `0.0`
	)

Constructor.

Builds TMatrix which blockdiagonals are smaller TMatrices.

Parameters

T0	TMatrix for upper block.
T1	Tmatrix for possible bottom block.

Member Function Documentation

◆ append()

template<class F >

void concepts::TMatrix< F >::append ( TColumn< F > * T )

inherited

Appends the columns to the matrix.

n_ is updated to reflect the real size of the matrix. m_ is updated to show the number of columns which are stored. The columns are scanned and the needed space is allocated. Then the new data is stored.

Parameters

T	a linked list of columns (in full notation) to be stored.

◆ applyOne()

template<class F >

void concepts::TMatrix< F >::applyOne	(	const ElementMatrix< F > &	A,
		ElementMatrix< F > &	B
	)		const

inherited

◆ columns()

template<class F >

TColumn<F>* concepts::TMatrix< F >::columns ( ) const

inherited

◆ control()

template<class F >

const TMatrix::Control* concepts::TMatrix< F >::control ( uint i ) const

inlineinherited

Returns the ith entry of the control data array.

Parameters

i	a colum index, i.e. i < n()

Definition at line 601 of file tmatrix.hh.

◆ data()

template<class F >

const TMatrix::Data* concepts::TMatrix< F >::data ( uint i ) const

inlineinherited

Returns the ith entry of the data array.

Definition at line 604 of file tmatrix.hh.

◆ extract() [1/2]

template<class F >

virtual void concepts::TMatrixBlock< F >::extract	(	const concepts::Vector< F > &	solution,
		concepts::Array< F > &	coeff
	)		const

inlinevirtual

Reimplemented from concepts::TMatrix< F >.

Definition at line 699 of file tmatrix.hh.

◆ extract() [2/2]

virtual void concepts::TMatrixBlock< F >::extract	(	const concepts::Vector<::std::complex< F > > &	solution,
		concepts::Array<::std::complex< F > > &	coeff
	)		const

inlinevirtual

Reimplemented from concepts::TMatrix< F >.

Definition at line 703 of file tmatrix.hh.

◆ extractOne()

template<class F >

void concepts::TMatrix< F >::extractOne	(	const concepts::Vector< F > &	solution,
		concepts::Array< F > &	coeff
	)		const

inherited

◆ index()

template<class F >

virtual uint concepts::TMatrix< F >::index ( const uint i ) const

inlinevirtualinherited

Mapping of the column index to the global degree of freedom.

Remember: the columns represent the global degrees of freedom to which the shape functions of this element contribute.

More technical: the columns of a TMatrix contain the column index in Control::idx and the relevant data in TMatrix::Data but the number of columns stored in TMatrixBase::n_ does not reflect the global number of degrees of freedom. Therefore, there might be empty columns and TMatrixBase::n_ could be lower than the global number of degrees of freedom.

◆ nEntries()

template<class F >

uint concepts::TMatrix< F >::nEntries ( ) const

inlineinherited

number of entries in the data vector

Definition at line 610 of file tmatrix.hh.

◆ offsetrow()

template<class F >

uint concepts::TMatrixBlock< F >::offsetrow ( ) const

inline

Returns the offset row, that is starting row of the (possible) second matrix block.

Definition at line 711 of file tmatrix.hh.

◆ operator()() [1/3]

template<class F >

void concepts::TMatrix< F >::operator()	(	const ElementMatrix< F > &	A,
		ElementMatrix< F > &	B
	)		const

inherited

Application operator.

Computes the application of the T matrix on A and returns B: $B = A \cdot T$ . The typical usage is explained in the base class.

More detailed: B is resized to a $n_A \times m_T$ matrix, then $B_{ij} = \sum_k A_{ik} T_{kj}$ where $i=1,\dots,n_A$ and $j=1,\dots,m_T$ and $\sum_k$ means sum over all which are present in the T matrix.

Parameters

A	Element matrix
B	Result

See also: T for the typical usage of this application operator.
