    Hello,

    I sent a mail to to the list regarding the van der Pol example.
    https://sourceforge.net/mailarchive/message.php?msg_id=27339310

    There is something wrong with the backward and forward continuation parts.
    If I skip this parts I can show() the figures form the limit cycle.

    Anyway there is a comment for the curve UD2, which is broken…

    Are there further sources/reference material besides the code?

    Kind regards,
    Guilherme

    Hi, thanks for your question.

    UD2 has been broken for a very long time. I'm not sure it ever worked. You'd have to contact the original authors (especially Drew Lamar). The error you saw has been fixed in a more recent release of PyDSTool, which skips the plot if 'UD' is not in pt.lables. Certainly, you could ensure this works by downloading from the BZR repository.

    You should look up the paper cited in the header of that script. I think this is a working link to it: www.people.wm.edu/~mdlama/publications/continuation.pdf

    I can't really help with the matplotlib problem, you'd need to ask on their mailing list. The -m32 option fix is already described in the Getting Started documentation for people with 64 bit machines. Also, I'm currently the only active developer but I'm happy to help with your code problems.
