! 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.
