_CBABK2(3F)							   _CBABK2(3F)

NAME
     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.

SYNOPSYS
	  subroutine  cbabk2(nm, n, low, igh, scale, m, zr, zi)
	  integer	   nm, n, low, igh, m
	  double precision scale(n), zr(nm,m), zi(nm,m)

	  subroutine scbabk2(nm, n, low, igh, scale, m, zr, zi)
	  integer	   nm, n, low, igh, m
	  real		   scale(n), zr(nm,m), zi(nm,m)

DESCRIPTION
     On INPUT

     NM must be set to the row dimension of two-dimensional array parameters
     as declared in the calling program dimension statement.

     N is the order of the matrix.

     LOW and IGH are integers determined by  CBAL.

     SCALE contains information determining the permutations and scaling
     factors used by  CBAL.

     M is the number of eigenvectors to be back transformed.

     ZR and ZI contain the real and imaginary parts, respectively, of the
     eigenvectors to be back transformed in their first M columns.  On OUTPUT

     ZR 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
