I am running two simulink model from matlab script(with "sim" command),,now i want to pause the running simulink model in the middle and send the data from "to workspace block" to my matlab workspace at the time wen i paused it,,,,,actually my requirmnet is meeting if i directly run my simulink model from simulnk start pause button,,,but its not working through script

I am running the simulink model with a script file I am taking a for loop, after 1 cycle value model runs but in next cycle value it deleted the old value. figure I can use using 'hold on' but how to store and retain old array?

Use
set_param('Yourmodel','Simulationcommand','start')
and your data will be saved to workspace

Maybe you should close a loop then start another loop, I did'nt try it (I have'nt Matlab where I am).

Arun, I tested your problem in a loop, and it worked, the initial value of the unit delay don't change when you pause simulation. I don't know why it don't work for you.

@Arun, I hope that you don't have any strange varsion of matlab (like Matlab R. Strange).
sim() command will not return till simulation is completed, so off-course your script will never go ahead to execute other commands like pause.
And, see below snap. When I run and pause the model from script using SimulationCommand, then To Workspace block output is saved in workspace. It should work for you also.

In your code, you are starting the simulation and then setting the stop time. I don't think this is proper way of simulating model.
Ok...One more try....
Can you explain what you are trying to do i simple words, so anyone here can suggest something.

Mr TAB My Strange MATLAB works propely ,,and it will not send values back to workspace until for loop will finish

If you want to set stop time, do it before start sim or after pause sim. It does'nt make sens to do it after start sim. Other thing, are you sur you are runing your model from m file, if yes, why are you then, using assignin command?

assignin am using to plot it and to put in to base workspace,,so that my other simulink model can access the data which are available from these models output

Arun, If speed_F is the output of another simulink model, that means that this variable is already in workspace, if not, then just use to workspace block
Arun Badigannavar

no actually these value in workspace i get wen i stop the model,,rather i want to get the data of workspace,when i pause the simulation
Azzi Abdelmalek

I do'nt understand. Even you pause your simulation, your data will be in workspace.

I am controlling my simulink models in a for loop from matlab script,,so wen i pause the from script,,,its reall not giving values back to workspace,,,,,

HELLO Mr TAB,,,in your screenshot You have added a breakpoint so u r getting the values to workspace,,,
