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.
