Member Function Documentation

◆ typeName()

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

inlinestatic

Return a string type-name for the underlying matrix

Definition at line 25 of file fei_MatrixTraits_LinSysCore.hpp.

◆ setValues()

static int fei::MatrixTraits< LinearSystemCore >::setValues	(	LinearSystemCore *	lsc,
		double	scalar
	)

inlinestatic

Set a specified scalar value throughout the matrix.

Definition at line 40 of file fei_MatrixTraits_LinSysCore.hpp.

◆ getNumLocalRows()

static int fei::MatrixTraits< LinearSystemCore >::getNumLocalRows	(	LinearSystemCore *	lsc,
		int &	numRows
	)

inlinestatic

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

Definition at line 48 of file fei_MatrixTraits_LinSysCore.hpp.

◆ getRowLength()

static int fei::MatrixTraits< LinearSystemCore >::getRowLength	(	LinearSystemCore *	lsc,
		int	row,
		int &	length
	)

inlinestatic

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

Definition at line 56 of file fei_MatrixTraits_LinSysCore.hpp.

◆ copyOutRow()

static int fei::MatrixTraits< LinearSystemCore >::copyOutRow	(	LinearSystemCore *	lsc,
		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

lsc
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 73 of file fei_MatrixTraits_LinSysCore.hpp.

◆ putValuesIn()

static int fei::MatrixTraits< LinearSystemCore >::putValuesIn	(	LinearSystemCore *	lsc,
		int	numRows,
		const int *	rows,
		int	numCols,
		const int *	cols,
		const double const	values,
		bool	sum_into
	)

inlinestatic

Sum a C-style table of coefficient data into the underlying matrix.

Definition at line 82 of file fei_MatrixTraits_LinSysCore.hpp.

◆ globalAssemble()

static int fei::MatrixTraits< LinearSystemCore >::globalAssemble ( LinearSystemCore * lsc )

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.
