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

I mean to say i have to write for loop again

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.

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,,,,,
