Re: Displaying results in GUI

Ok so my understanding is that you have a function that you've
written that returns a numerical result which you want to display in
a gui. At some point you need to signal to your gui to do the
computation and display the result. There are a few ways you can do
this. I'll describe two which I use most often. One way is in the
gui's opening function ( called guiName_OpeningFcn(hObject,
eventdata, handles, varargin) ). Here you can call your function and
display the result as soon as the gui loads. Or, you could use a
button in the gui which tells the gui to do your process and display
the result.

Let's say we've set up the gui as follows:
We have a textbox whose tag property is: textbox
We have a pushbutton whose tag property is: btnGo
We have named the function you wish to call: foo()

Now you would add this to the body of the opening function should you
choose to execute the command and display the results as soon as the
gui loads:

set(handles.textbox, 'String', foo());

or if you need to use foo's result later on:

result = foo();
set(handles.textbox, 'String', result);

If you choose to do the computation and display upon the pushing of a
button, you would need this code to appear:

function btnGo_Callback(hObject, eventdata, handles)
result = foo();
set(handles.textbox, 'String', result);

I hope this helps.
