You can use the set_param function to set these parameters before running the sim function. Something like below:
set_param('model_name', 'SolverType','Fixed-step');
sim('model_name');
You can set all the parameters individually and run sim at the end.

thank you, yes, after add the sim('model_name'), the model will run with the new confiuared parameter, but the parameter will turn back to default value when simulation stop, but any way it is ok.

You can use the save_system function to save the model after making changes.
