Constructor & Destructor Documentation

◆ flexMatrix()

template<typename T>

flexMatrix< T >::flexMatrix	(	int	aNumRows,
		int	aNumCols,
		bool	aMinus
	)

inline

initializes a matrix

Parameters

aNumRows	number of rows
aNumCols	number of cols
aMinus	determines if operator is negated

See also: isMinus

Member Function Documentation

◆ blockInsert()

template<typename T>

void flexMatrix< T >::blockInsert	(	std::vector< int > &	indexI,
		const std::vector< int > &	indexJ,
		const Tdata &	indexVal
	)

inline

inserts data into matrix

this is the fastest way to fill flexMatrix

Parameters

indexI	vector of row indices
indexJ	vector of column indices
indexVal	vector of data corresponding row and column indices

◆ copy()

template<typename T>

flexMatrix<T>* flexMatrix< T >::copy ( )

inlinevirtual

copies the linear operator

Returns: copy of linear operator

Implements flexLinearOperator< T >.

◆ getAbsRowSum()

template<typename T>

std::vector<T> flexMatrix< T >::getAbsRowSum ( bool transposed )

inlinevirtual

returns a vector of sum of absolute values per row used for preconditioning

Parameters

transposed is true if operator should be (temporarily) transposed before usage

Returns: vector of sum of absolute values per row

Implements flexLinearOperator< T >.

◆ getAbsRowSumCUDA()

template<typename T>

thrust::device_vector<T> flexMatrix< T >::getAbsRowSumCUDA ( bool transposed )

inlinevirtual

same function as getAbsRowSum() but implemented in CUDA

Parameters

transposed is true if operator should be (temporarily) transposed before usage

Returns: vector of sum of absolute values per row

Implements flexLinearOperator< T >.

◆ getMaxRowSumAbs()

template<typename T>

T flexMatrix< T >::getMaxRowSumAbs ( bool transposed )

inlinevirtual

returns the maximum sum of absolute values per row used for preconditioning

Parameters

transposed is true if operator should be (temporarily) transposed before usage

Returns: maximum sum of absolute values per row

Implements flexLinearOperator< T >.

◆ printRow()

template<typename T>

void flexMatrix< T >::printRow ( int i )

inline

prints requested row

Parameters

i	row to be printed

◆ times()

template<typename T>

void flexMatrix< T >::times	(	bool	transposed,
		const Tdata &	input,

equals $ y = y - Ax $

Parameters

transposed	is true if operator should be (temporarily) transposed before usage
input	data to be processed
output	output data

Implements flexLinearOperator< T >.

◆ timesPlus()

template<typename T>

void flexMatrix< T >::timesPlus	(	bool	transposed,
		const Tdata &	input,
		Tdata &	output
	)

inlinevirtual

applies linear operator on vector and adds its result to y

equals $ y = y + Ax $

Parameters

transposed	is true if operator should be (temporarily) transposed before usage
input	data to be processed
output	output data

Implements flexLinearOperator< T >.
