template<class F>
class concepts::ElementMatrix< F >

Element matrix.

This class stores the element matrix computed by a bilinear form. These matrices are assembled in a later step.

Member Function Documentation

add()

template<class F >

void concepts::ElementMatrix< F >::add	(	const ElementMatrix< F > &	A,
		uint	offm = 0,
		uint	offn = 0
	)

Addition of another element matrix with possible offset.

col()

template<class F >

uint concepts::ElementMatrix< F >::col ( ) const

inline

Returns current column.

Definition at line 309 of file element.hh.

compress()

template<class F >

void concepts::ElementMatrix< F >::compress

(

const Real

threshold = EPS

)

Compresses the matrix by dropping small entries.

All matrix entries which are smaller than a certain threshold times the largest entry of the matrix are deleted from the matrix.

getIndex()

template<class F >

int concepts::ElementMatrix< F >::getIndex ( ) const

inline

Deprecated:

: FIXME: what the heck is this even for?

Definition at line 289 of file element.hh.

info()

template<class F >

std::ostream& concepts::ElementMatrix< F >::info

(

std::ostream &

os

)

const

operator F*()

template<class F >

concepts::ElementMatrix< F >::operator F* ( )

inline

Returns a pointer to the data array.

Definition at line 298 of file element.hh.

operator()() [1/2]

template<class F >

F& concepts::ElementMatrix< F >::operator() ( const uint  i, const uint  j  )

inline

Definition at line 225 of file element.hh.

operator()() [2/2]

template<class F >

const F& concepts::ElementMatrix< F >::operator() ( const uint  i, const uint  j  ) const

inline

Returns element (i, j)

Definition at line 222 of file element.hh.

operator*=()

template<class F >

ElementMatrix<F>& concepts::ElementMatrix< F >::operator*= ( const F  n )

inline

Scaling operator.

Definition at line 301 of file element.hh.

operator=() [1/3]

template<class F >

template<class G >

ElementMatrix<F>& concepts::ElementMatrix< F >::operator= ( const ElementMatrix< G > &  other )

inline

can be used to upcast ElementMatrix<Real> to ElementMatrix<Cmplx>

Definition at line 236 of file element.hh.

operator=() [2/3]

template<class F >

ElementMatrix<F>& concepts::ElementMatrix< F >::operator=

(

const ElementMatrixBase< F > &

A

)

Assignement operator.

operator=() [3/3]

template<class F >

virtual ElementMatrix<F>& concepts::ElementMatrix< F >::operator= ( const F &  v )

inlinevirtual

Definition at line 246 of file element.hh.

resize()

template<class F >

virtual void concepts::ElementMatrix< F >::resize ( uint  m, uint  n  )

virtual

Sets a new size.

Previous data might be lost. The internal storage is set to the default row-major order.

row()

template<class F >

uint concepts::ElementMatrix< F >::row ( ) const

inline

Returns current row.

Definition at line 307 of file element.hh.

setIndex()

template<class F >

void concepts::ElementMatrix< F >::setIndex ( int  i )

inline

Deprecated:

: FIXME: what the heck is this even for?

Definition at line 292 of file element.hh.

setTranspose()

template<class F >

void concepts::ElementMatrix< F >::setTranspose ( bool  t )

inline

Sets the transpose status to t.

This does not anything if the matrix had the transpose status already. Otherwise, the dimensions are interchanged and the internal storage changes from row-major two column-major order or vice-versa.

Definition at line 286 of file element.hh.

transpose()

template<class F >

bool concepts::ElementMatrix< F >::transpose ( )

inline

Transposes the matrix.

Only the dimensions are interchanged, the data is not touched, but the internal storage changes from row-major two column-major order or vice-versa.

Deprecated:

use isTranspose() and setTranspose()

Definition at line 277 of file element.hh.

writeColumn() [1/3]

template<class F >

void concepts::ElementMatrix< F >::writeColumn	(	uint	col,
		const Array< F > &	val
	)

Writes an array to a column.

writeColumn() [2/3]

template<class F >

void concepts::ElementMatrix< F >::writeColumn	(	uint	col,
		const F	val
	)

Writes a value to a column in case of m() >= 1.

writeColumn() [3/3]

template<class F >

template<uint dim>

void concepts::ElementMatrix< F >::writeColumn	(	uint	col,
		const Point< F, dim > &	val
	)

Writes a vector to a column in case of m() >= dim.

Definition at line 326 of file element.hh.

zeros()

template<class F >

void concepts::ElementMatrix< F >::zeros ( )

inline

Fills the matrix with zeros.

Definition at line 295 of file element.hh.
