integer(i4b) function	petscmatrixmodule::pm_get_last_col_pos (this, irow)
integer(i4b) function	petscmatrixmodule::pm_get_column (this, ipos)
integer(i4b) function	petscmatrixmodule::pm_get_position (this, irow, icol)
	Return position index for (irow,icol) element in the matrix. This index can be used in other routines for direct access.
integer(i4b) function	petscmatrixmodule::pm_get_position_diag (this, irow)
subroutine	petscmatrixmodule::pm_zero_entries (this)
	Set all entries in the matrix to zero.
subroutine	petscmatrixmodule::pm_zero_row_offdiag (this, irow)
	Set all off-diagonal entries in the matrix to zero.
subroutine	petscmatrixmodule::pm_get_aij (this, ia, ja, amat)
subroutine	petscmatrixmodule::pm_get_aij_local (this, ia, ja, amat)
	Get the ia/ja and amat values for the local diagonal block of this matrix. It is a copy.
integer(i4b) function	petscmatrixmodule::pm_get_row_offset (this)
subroutine	petscmatrixmodule::pm_multiply (this, vec_x, vec_y)
	Calculates global matrix vector product: y = A * x.
