Is there a way to require ddesd to use a value from the previous time step?
Is there a way to use 'ddesd' or 'dde23' to evaluate y at the previous time step (by time step, I mean a full time step t+dt)? I...

How does ode45 handle highly coupled ODEs (where y' depends on x' and x' depends on y', etc.)?
After looking through many lines of code, I realize that the reason MATLAB is accepting an implicit equation without complaint i...

How does ode45 handle highly coupled ODEs (where y' depends on x' and x' depends on y', etc.)?
If I have two sets of highly coupled ODEs such as: dy/dt = A*dx/dt + B*y + C*x dx/dt = D*dy/dt + E*y + F*x or if I have...
