Accessing the value in each successful time step in ode45 solver
显示 更早的评论
I am trying to solve a second order ode with ode45 solver. I would like to get the value of the state variable in each successful time step.(by successful I mean the solver is based on an adaptive time step). Is there a way to get the value of the state variable in each successful time step while the solver is running and pass it to another function for a conditional check? Is it possible to save the values of the state variable in each successful time step and make it available to the workspace for further manipulation?

I may suggest you to go with event function of ode45.
The output of the ODE integrators contain the value of the state variable in each time step already. So why do you want something else?
Passing a variable for a "conditional check" is not clear. What kind of reaction to this check are you thinking of? Where should this check be considered?
