Do I have to import an array into function workspace?

Hello,

i want to use a function that refers to an Array ("Auswahl") in the base Workspace. The code is

function choice = Parameterwahl
d=dialog('Position',[500 400 300 150],'Name','');
txt = uicontrol('Parent',d,'Style','text','Position',[-52 80 400 40],...
              'String','Choose color','FontSize',12);
popup = uicontrol('Parent',d,'Style','popup','Position',[75 70 150 25],...
                'String', *Auswahl*,'Callback',@popup_callback);
btn = uicontrol('Parent',d,'Position',[89 20 70 25],'String','Ok',...
              'Callback','delete(gcf)');
uiwait(d);
     function popup_callback(popup,callbackdata)
        idx = popup.Value;
        popup_items = popup.String;
        choice = char(popup_items(idx,:));
     end
end

In the main script I call the function with "Parameterwahl" and Matlab seems to have a Problem with getting the Content of the Array "Auswahl" - the dropdownbox doesnt Show up, which does the Dialog is run in the main script. Do I have to Import the Array into the Workspace of the Parameterwahl.m-file ?

Thanks in advance.

Hi laboratoryassist,

every function got its own workspace and it is also different from the "base" workspace that you can see when using the command line.

=> mathworks documentation: base and function workspace

but it is still possible to get access to the base workspace, a similar question has been asked and answered.

This might help you.
