use psb_d_base_mat_mod
type, extends(psb_d_base_sparse_mat) :: psb_d_ell_sparse_mat
!
! ITPACK/ELL format, extended.
! Based on M. Heroux "A proposal for a sparse BLAS toolkit".
! IRN is our addition, should help in transferring to/from
! other formats (should come in handy for GPUs).
! Notes:
! 1. JA holds the column indices, padded with the row index.
! 2. VAL holds the coefficients, padded with zeros
! 3. IDIAG hold the position of the diagonal element
! or 0 if it is not there, but is only relevant for
! triangular matrices. In particular, a unit triangular matrix
! will have IDIAG==0.
! 4. IRN holds the actual number of nonzeros stored in each row
! 5. Within a row, the indices are sorted for use of SV.
