Scipy devels, The new odes scikit code is available from http://pypi.python.org/pypi/scikits.odes/1.0.0 and https://github.com/bmcage/odes which is tested with python 2.7 and 3.2. I don't think I'm allowed to remove the old scikit code in the svn repo at http://projects.scipy.org/scikits/browser/trunk/odes Can somebody delete those so as to avoid confusion? For those interested in the DAE and ODE api, see short examples: https://github.com/bmcage/odes/blob/master/docs/src/examples/ode/simpleoscil... https://github.com/bmcage/odes/blob/master/docs/src/examples/simpleoscillato...
