Functions
std::ostream &	mfem::operator<< (std::ostream &os, SparseMatrix const &mat)
void	mfem::SparseMatrixFunction (SparseMatrix &S, real_t(*f)(real_t))
	Applies f() to each element of the matrix (after it is finalized).
SparseMatrix *	mfem::Transpose (const SparseMatrix &A)
	Transpose of a sparse matrix. A must be finalized.
SparseMatrix *	mfem::TransposeAbstractSparseMatrix (const AbstractSparseMatrix &A, int useActualWidth)
	Transpose of a sparse matrix. A does not need to be a CSR matrix.
SparseMatrix *	mfem::Mult (const SparseMatrix &A, const SparseMatrix &B, SparseMatrix *OAB=NULL)
	Matrix product A.B.
SparseMatrix *	mfem::TransposeMult (const SparseMatrix &A, const SparseMatrix &B)
	C = A^T B.
SparseMatrix *	mfem::MultAbstractSparseMatrix (const AbstractSparseMatrix &A, const AbstractSparseMatrix &B)
	Matrix product of sparse matrices. A and B do not need to be CSR matrices.
DenseMatrix *	mfem::Mult (const SparseMatrix &A, DenseMatrix &B)
	Matrix product A.B.
DenseMatrix *	mfem::RAP (const SparseMatrix &A, DenseMatrix &P)
	RAP matrix product (with R=P^T)

SparseMatrix *	mfem::RAP (const SparseMatrix &A, const SparseMatrix &R, SparseMatrix *ORAP)
SparseMatrix *	mfem::RAP (const SparseMatrix &Rt, const SparseMatrix &A, const SparseMatrix &P)
	General RAP with given R^T, A and P.
SparseMatrix *	mfem::Mult_AtDA (const SparseMatrix &A, const Vector &D, SparseMatrix *OAtDA=NULL)
	Matrix multiplication A^t D A. All matrices must be finalized.
