◆ addGraphEntries()

void fei::Reducer::addGraphEntries ( fei::SharedPtr< fei::SparseRowGraph > matrixGraph )

Set the matrix-graph structure. This is the nonzero structure for locally-owned matrix rows.

		const int *	rows,
		int	numCols,
		const int *	cols,
		const double const	values,
		bool	sum_into,
		fei::Matrix &	feimat,
		int	format )

Put a C-style table (array of pointers) of coefficient data into the matrix. This is a rectangular array of coefficients for rows/columns defined by the 'rows' and 'cols' lists. If the sum_into argument is true, values should be added to any that already exist at the specified locations. Otherwise (if sum_into is false) incoming values should overwrite already-existing values.

		const int *	globalIndices,
		const double *	values,
		bool	sum_into,
		bool	soln_vector,
		int	vectorIndex,
		fei::Vector &	feivec )

Put coefficient data into a vector at the specified global indices. If any specified indices are out of range (negative or too large) the corresponding positions in the values array will not be referenced, and a positive warning code will be returned.

Parameters

numValues	Length of caller-allocated 'globalIndices' and 'values' arrays.
globalIndices	List of global-indices specifying the locations in the vector for incoming values to be placed.
values	List of incoming values.
sum_into	If true, incoming values should be added to values that may already be in the specified locations. If sum_into is false, then incoming values should overwrite existing values.
soln_vector	If true, incoming values should be placed in the solution vector. Otherwise, they should be placed in the rhs vector.
vectorIndex	If the linear system has multiple rhs/soln vectors, then this parameter specifies which vector the incoming values should be put into.
