Public Member Functions
	PETScMatrixOption ()

Public Attributes
bool	is_global_size
	Flag for the type of size, which is one of arguments of the constructor of class PETScMatrix true: the size is the number of local rows, false: the size is the number of global rows. The default is false.

PetscInt	n_local_cols
	Number of local columns. The default is PETSC_DECIDE.

PetscInt	d_nz
	Number of nonzeros per row in the diagonal portion of local submatrix (same value is used for all local rows), the default is PETSC_DECIDE.

PetscInt	o_nz
	Number of nonzeros per row in the off-diagonal portion of local submatrix (same value is used for all local rows), the default is PETSC_DECIDE.
