Real-Time GUI output into Simulink block

Hi,

I am trying to integrate between a GUI and simulink. And I expected an output from the GUI as the input for my simulink. But the problem is, I need to close my GUI everytime after I get an output from that, the reopen the GUI to get another set of output. And everything is saved in Result.mat as commanded in GUI. FYI, i am using MATLAB 2011 version

         save('Result','input2','color2','code2','code3','probsad','probhappy','probnervous','emotionNB','     datas','AutomataInput','Inputs')

For your information, I expected the AutomataInput variable (a constant) as the output from the GUI. Since I use 'from workspace' block, it requires at least 2x2 matrix as the input for my simulink. So I make a 2x2 matrix from the AutomataInput and name it is Inputs.

My question is 1. Instead of using 'from workspace' block, is there any other block I can use to integrate the GUI and simulink? 2. Instead of saving the GUI output in Result.mat and close the GUI everytime I get a set of output, is there any other way to make my system in real-time, I mean, whenever I change the input for GUI, the output will also change, and it will cause the input for my simulink change.

Thank you very much for your help.
