NAME
     ELTRAN, SELTRAN  -  EISPACK routine.  This subroutine accumulates the
     stabilized elementary similarity transformations used in the reduction of
     a REAL GENERAL matrix to upper Hessenberg form by  ELMHES.


SYNOPSYS
          subroutine  eltran(nm, n, low, igh, a, int, z)
          integer          nm, n, low, igh, int(igh)
          double precision a(nm,igh), z(nm,n)

          subroutine seltran(nm, n, low, igh, a, int, z)
          integer          nm, n, low, igh, int(igh)
          real             a(nm,igh), z(nm,n)



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 the balancing subroutine  BALANC.
     If  BALANC  has not been used, set LOW=1, IGH=N.

     A contains the multipliers which were used in the reduction by  ELMHES
     in its lower triangle below the subdiagonal.

     INT contains information on the rows and columns interchanged in the
     reduction by  ELMHES.  only elements LOW through IGH are used.  On OUTPUT

     Z contains the transformation matrix produced in the reduction by
     ELMHES.  Questions and comments should be directed to B. S. Garbow,
