Hi Matthias,
Thank you - now dmrg gives the correct results!
Unfortunately there is still one (but probably unrelated) problem with dmrg (I am working on a Debian Lenny system - Intel Xeon): Depending on the parameters I choose (some special model parameters, Number of MAXSTATES, etc.) in the parameter file, I sometimes get segmentation faults at the beginning or at the end. Sorry - I haven't figured out yet, when this happens exactly, but maybe somebody has observed similar errors...
Best, Sebastian

Hi,
I am having some trouble with the dmrg-program (e.g. of current ALPS 2.0b3) and "complex-valued" models. It seems to me that dmrg ignores the imaginary part of model-parameters (even with COMPLEX set to true). "sparsediag" gives the correct results.
Is this a bug or a general restriction of the dmrg-program? Or is it just a problem of my model or my local installation?
Thanks in advance and greetings, Sebastian
Hi Sebastian,
I fixed one bug and the fix will show up in the MacOS and source versions of thennext nightly snapshot (Friday morning). Can you please try that?
