NNNNAAAAMMMMEEEE
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.

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 the balancing subroutine BALANC.
If BALANC has not been used, set LOW=1, IGH=N.
AAAA contains the multipliers which were used in the reduction by ELMHES
in its lower triangle below the subdiagonal.
IIIINNNNTTTT contains information on the rows and columns interchanged in the
reduction by ELMHES. only elements LOW through IGH are used. On OUTPUT
ZZZZ contains the transformation matrix produced in the reduction by
ELMHES. Questions and comments should be directed to B. S. Garbow,
APPLIED MATHEMATICS DIVISION, ARGONNE NATIONAL LABORATORY
