I just want to draw attention to the bug report in <a href="http://projects.scipy.org/scipy/ticket/1187" target="_blank">http://projects.scipy.org/scipy/ticket/1187</a>. Basically, scipy.integrate.ode takes a function as input, and the error occurs if that function returns a tuple (instead of, e.g., a list).<br>
<br>If there isn&#39;t a simple fix (I can&#39;t tell b/c the error occurs within C-code, which I&#39;m not at all proficient in), then I think this should print a more informative error message.<br><br>Best,<br>-Tony<br>
