  Details of the permutations and scaling factors applied
          to the left side of A and B.  If P(j) is the index of the
          row interchanged with row j, and D(j) is the scaling
          factor applied to row j, then
            LSCALE(j) = P(j)    for j = 1,...,ILO-1
                      = D(j)    for j = ILO,...,IHI
                      = P(j)    for j = IHI+1,...,N.
          The order in which the interchanges are made is N to
          IHI+1, then 1 to ILO-1.
