How do I get an ODExx to return intermediate computed variables to the base workspace?

Using any of the ODE solvers, I would like to pass out intermediate calculations that are computed by my ODE function to the base workspace for post analysis.

There are a few ways to do this. If you want to pass out calculations that occur

on any of the time steps, successful or not, you may use Global variables or the function ASSIGNIN in your ODE function to pass the variables out to the base workspace.

If, however, you only want successful time step results, you may use the output function (outputFcn) in conjunction with ASSIGNIN or Global variables. You may need to recompute the calculations, however, in this method.
