communication between simulink and matlab gui
Andrea Monastero
I've got a matlab GUI. I want to read outputs of some
simulink blocks from the GUI program and update in real-time
some values of text boxes of the GUI. How can I do?
Thanks.

Hai,
You can write the Simulink Block output values into a .mat
file using 'To File' block and read the same file from the
matlab GUI.
or else similarly you can also make use of 'To Workspace'
block and then read the workspace parameters from the matlab
GUI.
Regards,
Ashwini

the GUI with the command "sim(...)", I've got to wait the
end of the simulation before execute the instruction which
reads the file. I need a real time response...

Use set_param(bdroot, 'SimulationCommand', 'Start') to run
the simulation asynchronously.

values that are being generated by a simulink model? Like
having a scope but within a GUI screen?

Yes of course. Add a call-back function to your GUI returning
the handles of the UI objects. Write an M-file S-function with
the Simulink signals as input. Query and cache the UI object
handles in the StartFcn, then update the UI objects in the
mdlUpdate procedure. Done that, works like a charm.

Hello Elizabeth
Could you be kind to post an example for plotting realtime
graphs in GUI

Dear Ralph, Dear Elizabeth,
could you exemplify that problem ...
"Add a call-back function to your GUI returning

or provide mor detail
Thanks in advance

hey..Regarding the that u wanted take real time data from simulink to GUI..I am currently doing something related to this..but i dun have any idea..
can u give some example of code?

Another approach, available in more recent versions of Simulink, is to add listeners on blocks using the function add_exec_event_listener.
(I'm not sure when that function was introduced but it exists in R2008b.)
I have uploaded an example UI/model using this approach to the file exchange:

could u post an example of this metod? (use s function insted event listener)

Hello,
I followed your example and it works very nice, thank you for that. However now I need to access both signals from XYGraph block? Could you tell me how to do that? I changed
sTime = block.CurrentTime;
into:
sTime=block.InputPort(2).Data;
In localEventListener function, but now both variables: sTime and data have the same values. What am I doing wrong?
