How to setting the simulation step in command window

Thanks in advance, any comments will be appreicate。

① I want use Command window let the simulation stepforward for two step, then stepbackward for 3 step, how to achieve it.

② As you know, we can set the simulation command as below:

set_param('VOL_Main','SimulationCommand','start');

set_param('VOL_Main','SimulationCommand','pause');

set_param('VOL_Main','SimulationCommand','continue');

set_param('VOL_Main','SimulationCommand','update');

set_param('VOL_Main','SimulationCommand','stop');

Except for these five command, does anybody can tell me all the command we can use after SimulationCommand.

③ How can I enable stepping back through Command window

④ How can I use the parameter 'tt' as the pause time in the Simulation stepping back window before i define it in the command window. Thanks again!

1. To achieve step forward, you could follow the step on this page: https://www.mathworks.com/matlabcentral/answers/302546-is-there-a-command-line-way-to-step-forward-and-backward-in-my-simulink-model-in-the-same-way-that-t

2. You can use 'set_param' to programmatically control a model simulation. More information can be found in the documentation here: https://www.mathworks.com/help/simulink/ug/control-simulations-programmatically.html

3. For stepping back, I believe there is no commands to achieve so in time. And the stepper cannot handle undefined function or variable as the pause time.
