Constructor & Destructor Documentation

mfem::STRUMPACKRowLocMatrix::STRUMPACKRowLocMatrix	(	MPI_Comm	comm,
		int	num_loc_rows,
		int	first_loc_row,
		int	glob_nrows,
		int	glob_ncols,
		int *	I,
		int *	J,
		double *	data
	)

Creates a general parallel matrix from a local CSR matrix on each processor described by the I, J and data arrays. The local matrix should be of size (local) nrows by (global) glob_ncols. The new parallel matrix contains copies of all input arrays (so they can be deleted).

Definition at line 25 of file strumpack.cpp.

mfem::STRUMPACKRowLocMatrix::STRUMPACKRowLocMatrix ( const HypreParMatrix & hypParMat )

Creates a copy of the parallel matrix hypParMat in STRUMPACK's RowLoc format. All data is copied so the original matrix may be deleted.
