How do I automatically run a MatLab Script when I start my simulation in simulink

103 vues (au cours des 30 derniers jours)
I have a simulink model and it uses a bunch of variables. I also have a script that sets initial values for the variables. I currently run the script before I start my simulation by typing "run scriptname" at the MatLab prompt (or by righ clicking the script file and selecting "run"). I would like this script to automatically run when I start my simulations. I've read the documentation on callbacks in the model properties dialog. I have placed the callback under the StartFcn callback (I've tried just putting the script name, both with and without the .m suffix. )...It didn't run. I've tried it in the InitFcn callback. I've tried loading it in the PreLoadFcn callback. Nothing seems to cause it to run. Does anyone know how to use these callbacks or how I would run a .m file prior to starting my simulation (besides doing it by hand and typing it in at the MatLab prompt?

just put the name without m in the InitFcn.

hi ...though replying on a old post but just for info,,,error might be because of the fact that your current matlab working directory is not set to the path where you have saved your model and script file.

Use the InitFcn callback.
If you want the M-script to run every time you run the simulation, InitFcn is the right one.

just put in "scriptname" without the double quotes.

From the error, it looks like the function is not on the path. Make sure that the function is in the current directory, or added to the MATLAB path.
