On exit: details of the permutations and scaling factors applied to the left side of the matrices
A and
B. If
Pi is the index of the row interchanged with row
i and
di is the scaling factor applied to row
i, then
- LSCALEi=Pi, for i=1,2,…,ilo-1;
- LSCALEi=di, for i=ilo,…,ihi;
- LSCALEi=Pi, for i=ihi+1,…,n.
The order in which the interchanges are made is n to ihi+1, then 1 to ilo-1.
