Hi, I am trying to use matlab compiler to create a standalone application out of my GUI. Unfortunately in the GUI I must use 'sim' and 'simset' to call some simulink model. Does anyone have an idea how to work this out?
Thanks a lot! Jerry

In R2020a, a new product Simulink Compiler has been released to address this exact use case. See an example here.

The SIM and SIMSET command can not be called from the MATLAB Compiler (This is documented here). To build a standalone GUI that runs your simulation, you need to make the simulation standalone, then build the GUI to run that.
This can be accomplished by using Simulink Coder (or Real-Time Workshop in earlier released) to build a standalone executable. This executable can be called by the GUI to run. The outputs of the simulation executable can be loaded by the GUI and analyzed.
A similar question was asked to Technical Support, and they published a solution: How can I create a standalone executable of a MATLAB GUI which calls a Simulink model?

The sim command is an unsupported command for the MATLAB Compiler and cannot be compiled.
The general strategy in such cases is to you use Simulink Coder to generated an executable out of the Simulink model which you can then control from the GUI.

Thank you, Chirag Gupta and Seth Popinchalk! But how can I change the simulation parameters such as solver and step size etc?

Hi. In this day, I'm having the same problem. I found this thread perfectly relevant to my problem. Obviously, there is another problem. All of the proposed links are not available. :( Could you help me, please.

Is it possible to call Simulink.saveVars function? In case it is not, how could I call this function from a standalone application?
