communication between simulink and matlab gui

Andrea Monastero — Wed, 30 Apr 2008 10:20:03 -0400

Hi.
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.

Ashwini

Yes I know, but in this way, if I run the simulation from
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.

Is there a way to plot in a GUI window, realtime, the
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
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. "

or provide mor detail

Thanks in advance
