Schur decomposition

[Marco Schauer]

Dear PETSc developers,
I translate a sequential Fortran code, which uses LAPACK into a parallel 
c++ code based on PETSc 3.0.0-p7. The Fortran code uses a function 
called DGEES to calculate Schur decomposition. I have absolutely no idea 
how to do this in PETSc. Is there a PETSc example of this problem? Every 
hint is very welcome to me.
Best regards
Marco
