I am using ode15s to solve a set of differential equation on the form M(t,y)dy/dt = f(t,y). Due to the way I have formulated my ode's now, I need to use the time step from ode15s inside the function f(t,y). As far as I can see, I only have access to the present time 't' when ode15s is working, but is there any way to work around this so I can use the time step dt?

If the function to be integrated requires the time steps of the solver, something went wrong. I'm convinced that this is a logical error in the implementation. Please explain, why you think you need this.

The question is 6 years old. I do not remember how I solved it, but I think I did. I at least do not need an answer to the question anymore.
