Several MATLAB ODE dy/dt = f(y,t) solvers (ode15s, ode23, ode113, ode23t, ode23tb, ode45, ode23s) have been connected to free OpenOpt Suite package (possibly with FuncDesigner automatic differentiation) in addition to scipy_lsoda (scipy.integrate.odeint), see the example . Currently only reltol parameter is available; future plans may include abstol, Python3 and PyPy support, solver ode15i for solving f(dy/dt, y, t) = 0, possibility to use single MATLAB session for several ODE probs. Sparse matrices handling is implemented for fmincon and fsolve but not ode solvers yet. ---------------------- Regards, D. http://openopt.org/Dmitrey
