You must stop or pause simultion before seting new parameters

i think this example in matlab 'Displaying Mechanical State Values During Simulation ' is doing so , but i can't get it

There are several ways.
  1. You can pause the simulation at any instant and go to the particular block parameters and change the values and play the simulation again. But you have to tolerate the pain of pausing the simulation at stipulated times and running again each time you have to change parameters. This is the easiest though. This doesn't use m file.
  2. Otherwise if your parameters are to be changed and you know the parameter values and time intervals beforehand, you can code them in Embedded MATLAB Function block. (Don't forget to include "eml.extrinsic('set_param');" in this block).
  3. Or (the best method) you can create a GUI if you are required to change the parameters continuously without pausing the simulation and when you don't know the time and parameter values beforehand. This is more versatile and less painful. You will have to code the GUI m file.
