I am automating the code generation process by using a .m script that uses rtwbuild('MyModel') to initiate the build. 'MyModel' references a 'ReferenceModel'. This 'RefrenceModel' uses the callback PreloadFcn to run 'MyParameters.m'
My problem is that when I use rtwbuild('MyModel'), 'MyParameters.m' is never run so the build process errors out because none of my parameters are defined.
If I run 'MyParameters.m' before rtwbuild('MyModel') it builds fine. However, I don't want to have to run 'MyParameters.m' before rtwbuild('MyModel'). I thought the PreloadFcn callback should work.
Am I doing something wrong? Or do callback functions not work in reference models for rtwbuild?
Thanks,

After researching the Callback in the help, I found this nugget of info: http://www.mathworks.com/help/simulink/ug/using-callback-functions.html
At the bottom it says to avoid 'run' commands in callback code. Good to know!
Removed the 'run' command, left the name of the m script.
It now builds perfectly!
