Thread Subject: GUI and m-files. Sharing data between them

Hi everybody,

I am developing a GUI for making a comparative between some
results, which are done in other m-files. This m-files also
need to change some parameters of a simulink model.

So, i have a GUI, some m-files, and a simulink model. The
GUI is not very complex, I have an axes figure for ploting
the simulation and a few buttons for selecting the
appropiate algorithm (this is, a call to a code stored in
one of the m-files, which will change parameters and
simulate the simulink model, and will produce some
variables).

Having said that, my problem is: I don't know how to pass
the data obtained from the m-files to the GUI, and then
work with them INSIDE the GUI. How can i do that?

I know i could use nested functions, but in that case the m-
file would be very big. Also some functions are .p
extension and i dont have access to the code.

I have looked on the web but i dont find an example or a
clear response (i know it's related with handles data).

Any help will be very useful.

Kind regards, Mario.

One way to do it is to use the application data commands. (getappdata(), setappdata(), etc)

Watch this little video:

I've been using this approach for a medium sized project I'm working on. There may be more elegant ways of handling the problem.

Thanks BogFrog,

In fact, i have seen that video today. I?ll reply if i
could figure out my problem. Anyway, if someone has any
other way for my problem it would be nice to know.

Thanks. Mario

Hai,

Another way is defining the variables as global so that u
can refer them from any m-files present in that folder. Just
 tryout ..if u cant make it out ... i will give u an example..
