I have a very detailed question,
in the below programs:
set_param('mdl','SimulationCommand','start')
set_param('mdl','SimulationCommand','pause')
set_param('mdl','SimulationCommand','Update')
set_param('mdl','SimulationCommand','continue')
when I use set_param('mdl','SimulationCommand','Update') does this command updates the mdl before next continue?Or updating will down in the end of next continuation?
Yes, this command is used for establish a value in a variable determined in the block at Simulink.
Only you must specify the path of the parameter you want to change.
You can control the simulation throught of code. The update is done until you stop the simulation.
I used this code :
set_param('mdl','SimulationCommand','start')
set_param('mdl','SimulationCommand','pause')
set_param('mdl','SimulationCommand','Update')
set_param('mdl','SimulationCommand','continue')
but when i run my simulation step by step my updated signal didn't change until the end of next step, after starting the simulation, it pauses in after 0.05 sec, I want to update a variable in the model, then continue for next 0.05 sec step, for example if K = 0 for first step i want to change it to 0.2 in the second step, but this structure updates K in the time 0.1(end of second step), how can i overcome this problem?
The Matlab help for set_param states, that you can update work-space variables using the Update argument. This seems however to hold only, when the simulation is running.
Maybe block callbacks can help you here, to solve the problem:

Good luck!
