I am trying to use the trevc.hpp header with my new  hseqr.hpp header.  I'm not getting the results I expected and I'm trying to track down the error.  Everything compiles and runs, but the result is not what I expected.  I can confirm the results of hseqr by a call to Mathematica, but I can't figure out an equivalent command for trevc.  

Does anyone have an example of trevc in use?

Thanks,
Jeremy
