Hello, i am assigned to do the following task but i am new to MatLab..
Create and launch a GUI when 'run' is pressed on simulink. The user will enter the desired input value on the GUI.The input value will change accordingly on the simulink.
For example, the user want to have 1Volt for the simulation, he will enter '1' on the GUI and the simulink parameter will change accordingly.
I have a constant block, a repeating sequence interpolateed block and a compare to constant block. I have to edit these 3 block using GUI.
Any suggestions? Thanks in advance!

Hi,
I understand that you want to create a GUI to change the value of the block parameters in simulink.
You can do this by creating an app in app designer with Edit Field components.
In the “ValueChangedFcn” of Edit Field components, you can use “set_param” function to set the value of your required Simulink block.
The syntax of “set_param” function is as follows,
set_param(‘modelName/BlockName’ , ‘BlockParameterName’, value);
If you want to launch the app after loading the model, app need to be launched from “PostLoadFcn” callback or else if you want to launch the app after hitting the “run” button, app need to be launched from “StartFcn” callback. You can find the callbacks in Model Properties.
