GUI-Simulink

Sir/Madam, I have two questions. 1. How to make a simulink model to stop simulation using a push button in GUI? am making use of sim command to start simutaion. Suppose the name of model is final_guidance_4.

2. In the same model mentioned above, I want user to input the value of forward velocity in GUI edit text box. this value is to be stored source block parameter "u" which would be a constant. Please guide me

Hi Nitesh,

you can use

set_param(gcs, 'SimulationCommand', 'start')

or

set_param(gcs, 'SimulationCommand', 'stop')

to start and stop the current simulink simulation

To change the value of a constant block simple write

u = 'something new';

Sir where to write u='something new". I mean I wanna connect it to the text of edit text box in my GUI??

In your simulink model use a constant block with a "constant value" of "u" Now "u" is a variable which you can change from the workspace or from a gui. In the callback of your edit text box simply write

u = str2num(get(editbox,'String')) and the value of "u" is changed by the GUI
