how to enter data to a simulink model while it is executing

I am running my simulink models from gui written in script in MATLAB ,Now i want to change some values of simulink model blocks which are user entering while the starting of the simulation,,but now i want to change them whenever user wants them to change,,,for this i should pause the simualtion or how will i allow user to enter his value at any time

If you don't need to change parameters while your model is running, it's better to stop your model. then use set_param function to change your parameters

[TAB]

@Arun: And only Tunable Parameters values can be changed while running simulation.

@TAB went through these tunable parameters ,,,thanks for it,,,

[Azzi Abdelmalek]

use these commands

 set_param('modelname','SimulationCommand','pause')

Then

 set_param('modelname/yourblock','param','value')

then

 set_param('modelname','SimulationCommand','continue')

If you want to stop simulation use

 set_param('ansm269','SimulationCommand','stop')

doc set_param
