For a problem of Amplitude Modulation, if I want to perform it on Simulink but get the various parameters like carrier freq. etc. from a companion m file, how do I do it ??

There are two ways to access variables from a .m file to Simulink.

1. Before running the Simulink model, run the .m file to save the variables in the workspace and access those variables using ‘From Workspace’ block in Simulink.
2. In order to run your m-file automatically when you run your Simulink model, add the m-file name to the ‘InitFcn’ callback in ‘Model Properties->Callbacks’ and use those variables in the Simulink model.
