! HLL format. (Hacked ELL)
|
|
! A modification of ELL.
|
|
! Basic idea: pack and pad data in blocks of HCK rows;
|
|
! this reduces the impact of a lone, very long row.
|
|
! 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.
|
|
! 6. hksz: hack size (multiple of 32)
|
|
! 7. hkoffs(:): offsets of the starts of hacks inside ja/val
