S Function : How to output the derivatives

Hello,

I'm integrating the equations of a dynamic system with a S function. The code looks like that:

switch flag
     case 0
          % Initialization
     case 1
          % Here I calculate dV/dt
     case 3
          % Here I output the V calculated by the S function
%...
end

I would not only like to output V, but also the dV/dt calculated in case 1.

Is it possible?

Thank you.

I don't think this is possible in a Level-1 MATLAB S-function, but in a Level-2 MATLAB S-function, you might be able to create a Discrete State DWork and store the same value in it.
