Dear Colleague,

You can place the MATLAB Function block inside an Enabled Subsystem and control its execution using an enable signal.

The sim command only returns to MATLAB after the simulation is complete, so if you want to be able to pause simulation, you need to start simulation using set_param(bdroot,'SimulationCommand','start') so that control is immediately returned to MATLAB. You can then use the PAUSE command (say pause(5) if you want to run for 5secs) to let the model run for a short period, and then use set_param(bdroot,'SimulationCommand','pause') to pause simulation. Use set_param(bdroot,'SimulationCommand','stop') to stop simulation.

Please, see the attached links, to see the above and the following:

you might find the attached pdf file useful too.

Dear Abdollah Younesi

Using "Matlab Function" you can call m file "*.m" from simulink. You can pass any number of parameters to the Matlab Function and return any number of output signals.

it is found in simulink\User-Defiend functions.

You can use the "Matlab Function" block.

Hazim Hashim Tahir thanks for the answer.

%% Open model

open_system(ModelName);

%% Start simulation

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

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

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

%%Close simulation

close_system(ModelName)
