[ALPS-users] dmrg errors

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
