Hello, A quick followup on the subject of finding a Python wrapper for SUNDIALS. Good news is that there are a few projects that did it already. I will short review what I found. 1) python-sundials http://code.google.com/p/python-sundials/ Just a Cython wrapper around the original SUNDIALS code (

Dear all, I see that Sage has some ODE solvers from GNU Scientific Library. Is there any DAE solver readily available to Sage? I have here a second order nonlinear system which boils down to some system as: M(y) ydot = f(t,y) My mass matrix is state dependent, not time dependent (yet). It is als
