How to use set_param correctly in a function

When I execute the following program in a function, each process can be performed, but the data in the To workspace is not reflected in the base workspace.

What is the difference between this and script execution?

Also, is there a way to solve this problem?

set_param('vdp','SimulationCommand','pause')
set_param('vdp','SimulationCommand','continue')

The To Workspace block typically writes data to the MATLAB® base workspace. For a sim command in a MATLAB function, the To Workspace block sends data to the workspace of the calling function, not to the MATLAB base workspace. To send the logged data to the base workspace, use an assignin command in the function.

Can I also run Simulink to send data from the function workspace to the base workspace in real time?

[Walter Roberson]

No. Simulink does not send data to the base workspace until it ends or the simulation is paused .

Is there a way to pause/stop Simulink that I can run within a function?
