- BALBAK, SBALBAK - EISPACK rotuine. This subroutine forms the
- eigenvectors of a REAL GENERAL matrix by back transforming those of the
- corresponding balanced matrix determined by BALANC.

- 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 BALANC.
-
- SSSSCCCCAAAALLLLEEEE contains information determining the permutations and scaling
- factors used by BALANC.
-
- MMMM is the number of columns of Z to be back transformed.
-
- ZZZZ contains the real and imaginary parts of the eigen- vectors to be back
- transformed in its first M columns. On OUTPUT
-
- ZZZZ contains the real and imaginary parts of the transformed eigenvectors
- in its first M columns. Questions and comments should be directed to B.
