◆ getNumLocalRows() [1/2]

static int fei::MatrixTraits< FiniteElementData >::getNumLocalRows	(	FiniteElementData *	fed,
		int &	numRows )

inlinestatic

Query the number of rows. This is expected to be the number of rows on the local processor.

Definition at line 47 of file fei_MatrixTraits_FEData.hpp.

◆ getRowLength() [1/2]

static int fei::MatrixTraits< FiniteElementData >::getRowLength	(	FiniteElementData *	fed,
		int	row,
		int &	length )

inlinestatic

Given a global (zero-based) row number, query the length of that row.

Definition at line 55 of file fei_MatrixTraits_FEData.hpp.

◆ copyOutRow() [1/2]

static int fei::MatrixTraits< FiniteElementData >::copyOutRow	(	FiniteElementData *	fed,
		int	row,
		int	len,
		double *	coefs,
		int *	indices )

inlinestatic

Given a global (zero-based) row number, pass out a copy of the contents of that row.

Parameters

fed
row
len	Length of the user-allocated arrays coefs and indices.
coefs	User-allocated array which will hold matrix coefficients on output.
indices	User-allocated array which will hold column-indices on output.

Returns: error-code 0 if successful. Non-zero return-value may indicate that the specified row is not locally owned.

Definition at line 72 of file fei_MatrixTraits_FEData.hpp.

◆ putValuesIn() [1/2]

static int fei::MatrixTraits< FiniteElementData >::putValuesIn	(	FiniteElementData *	fed,

Definition at line 80 of file fei_MatrixTraits_FEData.hpp.

◆ globalAssemble() [1/2]

static int fei::MatrixTraits< FiniteElementData >::globalAssemble ( FiniteElementData * fed )

inlinestatic

Perform any necessary internal communications/synchronizations or other operations appropriate at end of data input. For some implementations this will be a no-op, so this "default implementation" will return 0.

Definition at line 93 of file fei_MatrixTraits_FEData.hpp.

◆ matvec() [1/2]

static int fei::MatrixTraits< FiniteElementData >::matvec	(	FiniteElementData *	fed,

		fei::Vector *	y )

inlinestatic

Compute the matrix-vector product y = A*x

Definition at line 99 of file fei_MatrixTraits_FEData.hpp.

◆ typeName() [2/2]

static const char * fei::MatrixTraits< FiniteElementData >::typeName ( )

inlinestatic

Return a string type-name for the underlying matrix. May appear in debug-output logs, etc. Does not need to exactly correspond to the type, but should be descriptive.

Definition at line 51 of file fei_MatrixTraits.hpp.

◆ getBeginPointer() [2/2]

static double * fei::MatrixTraits< FiniteElementData >::getBeginPointer ( FiniteElementData * )

inlinestatic

Definition at line 54 of file fei_MatrixTraits.hpp.

◆ setValues() [2/2]

static int fei::MatrixTraits< FiniteElementData >::setValues	(	FiniteElementData *	mat,
		double	scalar )

inlinestatic

Set a specified scalar value throughout the matrix.

◆ getNumLocalRows() [2/2]

static int fei::MatrixTraits< FiniteElementData >::getNumLocalRows	(	FiniteElementData *	mat,
		int &	numRows )

inlinestatic

Query the number of local rows. This is expected to be the number of point-entry rows on the local processor.

Definition at line 72 of file fei_MatrixTraits.hpp.

◆ getRowLength() [2/2]

static int fei::MatrixTraits< FiniteElementData >::getRowLength	(	FiniteElementData *	mat,
		int	row,
		int &	length )

inlinestatic

Given a locally-owned global row number, query the length (number of nonzeros) of that row.

Definition at line 78 of file fei_MatrixTraits.hpp.

◆ copyOutRow() [2/2]

static int fei::MatrixTraits< FiniteElementData >::copyOutRow	(	FiniteElementData *	mat,
		int	row,
		int	len,
		double *	coefs,
		int *	indices )

inlinestatic

Given a locally-owned global row number, pass out a copy of the contents of that row.

Parameters

mat
row	Global row number
len	Length of the user-allocated arrays coefs and indices.
coefs	User-allocated array which will hold matrix coefficients on output.
indices	User-allocated array which will hold column-indices on output.

Returns: error-code 0 if successful. Non-zero return-value may indicate that the specified row is not locally owned.

Definition at line 93 of file fei_MatrixTraits.hpp.

◆ putValuesIn() [2/2]

◆ globalAssemble() [2/2]

static int fei::MatrixTraits< FiniteElementData >::globalAssemble ( FiniteElementData * A )

inlinestatic

Perform any necessary internal communications/synchronizations or other operations appropriate at end of data input. For some implementations this will be a no-op, so this "default implementation" returns 0. (The Trilinos/Epetra traits specialization calls A->FillComplete() at this point.)

Definition at line 114 of file fei_MatrixTraits.hpp.

◆ matvec() [2/2]

static int fei::MatrixTraits< FiniteElementData >::matvec	(	FiniteElementData *	A,
		fei::Vector *	x,
		fei::Vector *	y )

inlinestatic

Compute the matrix-vector product y = A*x. It is expected that the underlying matrix object will form the local portion of the result 'y' on the local processor.
