◆ HypreParMatrix() [1/11]

mfem::HypreParMatrix::HypreParMatrix ( )

An empty matrix to be used as a reference to an existing matrix.

Definition at line 681 of file hypre.cpp.

◆ HypreParMatrix() [2/11]

mfem::HypreParMatrix::HypreParMatrix	(	hypre_ParCSRMatrix *	a,
		bool	owner = true )

inlineexplicit

Converts hypre's format to HypreParMatrix.

If owner is false, ownership of a is not transferred

		HYPRE_BigInt	glob_size,
		HYPRE_BigInt *	row_starts,

Creates block-diagonal square parallel matrix.

Diagonal is given by diag which must be in CSR format (finalized). The new HypreParMatrix does not take ownership of any of the input arrays. See here for a description of the row partitioning array row_starts.

Warning: The ordering of the columns in each row in *diag may be changed by this constructor to ensure that the first entry in each row is the diagonal one. This is expected by most hypre functions.

Definition at line 928 of file hypre.cpp.
