- CORTB, SCORTB - EISPACK routine. This subroutine forms the
- eigenvectors of a COMPLEX GENERAL matrix by back transforming those of
- the corresponding upper Hessenberg matrix determined by CORTH.

- On INPUT
-
- NNNNMMMM must be set to the row dimension of two-dimensional array parameters
- as declared in the calling program dimension statement.
-
- LLLLOOOOWWWW and IGH are integers determined by the balancing subroutine CBAL.
- If CBAL has not been used, set LOW=1 and IGH equal to the order of the
- matrix.
-
- AAAARRRR and AI contain information about the unitary transformations used in
- the reduction by CORTH in their strict lower triangles.
-
- OOOORRRRTTTTRRRR and ORTI contain further information about the transformations used
- in the reduction by CORTH. Only elements LOW through IGH are used.
-
- MMMM is the number of columns of ZR and ZI 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.
-
- OOOORRRRTTTTRRRR and ORTI have been altered. Note that CORTB preserves vector
- Euclidean norms. Questions and comments should be directed to B. S.
