- ORTRAN, SORTRAN - EISPACK routine. This subroutine accumulates the
- orthogonal similarity transformations used in the reduction of a REAL
- GENERAL matrix to upper Hessenberg form by ORTHES.

- 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 information about the orthogonal trans- formations used in the
- reduction by ORTHES in its strict lower triangle.
-
- OOOORRRRTTTT contains further information about the trans- formations used in the
- reduction by ORTHES. only elements LOW through IGH are USED. On OUTPUT
-
- ZZZZ contains the transformation matrix produced in the reduction by
- ORTHES.
-
- OOOORRRRTTTT has been altered. Questions and comments should be directed to B. S.
