simulink and gui across workspace

in simulinke model there is a "to workspace " assume its var is "sout" that i want this var "sout" identified by my gui program

Answer 1

Simulink data from To Workspace block is always saved in Matlab base workspace. So your variable "sout" will appear in matlab base workspace after the simulation.

You can access this variable in you GUI program (or in any other) function using

data = evalin('base','sout');

Using this, values in "sout" from base workspace will be copied in variable "data".

perfect ,that is very nice but if smulinke still running can i use the same expression

[TAB]

No. Simulink saves all the data through To Workspace block only after the completion of simulation. So this data will not be available during simulation.

that is a big problem ,i need another way to send data to my gui ?

If you want to access your data during simulation, please see http://www.mathworks.com/help/toolbox/simulink/ug/f13-92122.html

Alternatively, you could write a MATLAB S-function block that is connected at the appropriate signals to update your GUI.

done thanks for you all still simple problem this function make my gui slower and the function can not run when i run another thing in my gui

[TAB]

What another thing you are running in your GUI ?
