Hello Folks
I am trying to create a button that would launch "open file" functionality in order to save a ".mat" file , for use in the GUI.
the second issue i have, let's say i ahve popup menu that when one of its element is selected a certain algorithm is executed, this part i have done, but i want the algorithm function that has returned vector, to display one of its rows data in a text format in the GUI "say in a small frame"
i am using GUIDE. i am not sure if programmatic GUI works together with uicontrol object directly "i mean inside one of the function that gets generated in GUIDE"

tnks for ur response
for the second the problem i first did this
function popupmenu1_Callback(hObject, eventdata, handles)
str = get(hObject, 'String');
%val = get(hObject,'Value');
% Set current data to the selected data set.
switch str;
case 'Ellipsoidal Estimation' % User selects peaks.
Ellipsoidal_Algorithm;
case 'Recursive Least Square' % User selects membrane.
RLS_Algorithm;
end
% Save the handles structure.
guidata(hObject,handles)
that didn't cause the selection to launch the functions indicated in each switch case
then i did this
function Run_Callback(hObject, eventdata, handles)
str = get(hObject,'String');
CMP=strcmp(str,'Ellipsoidal Estimation');
if CMP==1
Ellipsoidal_Algorithm;
end
if CMP==0
RLS_Algorithm;
end
that didn't work either

You're not reading the value of the popup correctly. str = get(hObject,'String') will return all strings of the popup. In your case str = {'Ellipsoidal Estimation', 'Recursive Least Square'}. You will have to use v = get(hObject,'Value') to read at which position the popup is.
Did you try the solution I suggested here? http://www.mathworks.nl/matlabcentral/answers/32836-pop-up-menu-in-guide
I'm pretty sure that should work.

For first problem:
Write as Callback for your button this code:
[a,b] = uigetfile open([b,a])
