 by backward transformation on the computed eigenvectors of the
 balanced matrix output by SGEBAL.

\fIJOB\fP 
.PP
.nf
          JOB is CHARACTER*1
          Specifies the type of backward transformation required:
          = 'N', do nothing, return immediately;
          = 'P', do backward transformation for permutation only;
          = 'S', do backward transformation for scaling only;
          = 'B', do backward transformations for both permutation and
                 scaling.
          JOB must be the same as the argument JOB supplied to SGEBAL.

.nf
          SIDE is CHARACTER*1
          = 'R':  V contains right eigenvectors;
          = 'L':  V contains left eigenvectors.

.nf
          IHI is INTEGER
          The integers ILO and IHI determined by SGEBAL.

\fISCALE\fP

.nf
          SCALE is REAL array, dimension (N)

.nf
          V is REAL array, dimension (LDV,M)
          On entry, the matrix of right or left eigenvectors to be
          transformed, as returned by SHSEIN or STREVC.
          On exit, V is overwritten by the transformed eigenvectors.
