Function Documentation

SparseMatrix* Mult	(	SparseMatrix &	A,
		SparseMatrix &	B,
		SparseMatrix *	OAB = NULL
	)

Matrix product A.B. If OAB is not NULL, we assume it has the structure of A.B and store the result in OAB. If OAB is NULL, we create a new SparseMatrix to store the result and return a pointer to it. All matrices must be finalized.

SparseMatrix* Mult_AtDA	(	SparseMatrix &	A,
		Vector &	D,
		SparseMatrix *	OAtDA = NULL
	)

Matrix multiplication A^t D A. All matrices must be finalized.

SparseMatrix* RAP	(	SparseMatrix &	A,
		SparseMatrix &	R,
		SparseMatrix *	ORAP = NULL
	)

RAP matrix product. ORAP is like OAB above. All matrices must be finalized.
