Can we call a m-script during model simulation ?:

I want to run a script , which will update some of my parameters in the workspace. Is it possible to call a m-script during model simulation .

I have heard of call back functions like StartFnc and CloseFcn,

But my concern is, when a block is hit (active) in simulation , Can we can a script at that particular point ?

Is there any matlab block in simulink to call a m-script ?

Do you want to change some parameters in your Simulink model during simulation?

Yes

You can control your simulink model from a script file

set_param('modelname', 'SimulationCommand', 'start') % To start your simulation 
% Then change your parameters in workspace
set_param('modelname', 'SimulationCommand', 'update')  % will update your Simulink parameters

You can also change the parameters in your blocks by using set_param. Look at this example

I have used mask initialization of a sub-system and call m-script that will solve the purpose . But yes it will run only once at simulation start. Thanks for your comment !!
