Hi I have this problem. I've a simulink model that read data from workspace in real time execution. In such a way i'm able to produce a voltage output in order to obtain that a motor follows the desired trajectory that i compute in a m-file. Now the problem is: If i would like to change the trajectory while the simulation is running how can i make this using a from workspace block in the simulink model that is implemented via structure? I hope that my exposition is clear. Thanks everyoneю
