CBABK2, SCBABK2 - EISPACK routine. This subroutine forms the
eigenvectors of a COMPLEX GENERAL matrix by back transforming those of
the corresponding balanced matrix determined by CBAL.

On INPUT
NNNNMMMM must be set to the row dimension of two-dimensional array parameters
as declared in the calling program dimension statement.
NNNN is the order of the matrix.
LLLLOOOOWWWW and IGH are integers determined by CBAL.
SSSSCCCCAAAALLLLEEEE contains information determining the permutations and scaling
factors used by CBAL.
MMMM is the number of eigenvectors to be back transformed.
ZZZZRRRR and ZI contain the real and imaginary parts, respectively, of the
eigenvectors to be back transformed in their first M columns. On OUTPUT
ZZZZRRRR and ZI contain the real and imaginary parts, respectively, of the
transformed eigenvectors in their first M columns. Questions and
comments should be directed to B. S. Garbow, APPLIED MATHEMATICS
DIVISION, ARGONNE NATIONAL LABORATORY
