Simple question: Given a cell array of: CellArray(1,50)={zeros(10,N)}

1. The 10 refers to 10 popupmenu options 2. The N refers to listboxoptions

So it's popupmenu options x listbox options

How can I input 1's for the currently selected listbox and popupmenu options? For instance:

popupmenu option #3 is selected; listbox options 4, 5, 7 are selected;

I want to produce this in my matrix based on those selections:

0 0 0 0 0 0 0 0 0 ..... N 0.......N 1 0 0 0 1 1 0 1 0 0 0 ....N 0.......N . . . . Please let me know if I'm not explaining this clearly!

Is it that you have 10 popupmenus and N listboxes, or one popumenu and one listbox?

If you only have one of each, then shouldn't your array only have two ones in it?

Perhaps if you give a very small example...

EDIT In response to clarifying comments.

Here is an example, based on what you said. Note that the array is only displayed when a popup value is chosen, so select from the listbox first to fill in a column other than the first. You could alter this by putting the same code in the listbox callback...

function [] = pop_ex()
% Help goes here.
S.fh = figure('units','pixels',...
              'position',[10 30 120 140],...
              'menubar','none',...
              'name','slider_ex',...
              'numbertitle','off',...
              'resize','off');
S.pp = uicontrol('style','pop',...
                 'unit','pix',...
                 'position',[20 20 120 40],...
                 'string',{'one','two','three','four'},...
                 'callback',@pp_call); 
S.ls = uicontrol('style','list',...
                 'unit','pix',...
                 'position',[20 80 120 40],...
                 'string',{'lone','ltwo','lthree','lfour','lfive','lsix'});
guidata(S.fh,S)             
function [] = pp_call(varargin)
% Callback for the popup.
S = guidata(gcbf);
A = zeros(length(get(S.pp,'string')),length(get(S.ls,'string')));
R = get(S.pp,'val');
C = get(S.ls,'val');
I = sub2ind(size(A),[R R],[1 C]);
A(I) = 1  % Display in command window.

EDIT Address multi-selectable listboxes.

If the listbox is multi-selctable, then use this line instead:

I = sub2ind(size(A),[R repmat(R,1,length(C))],[1 C]);

I'm not sure if I understand that. So are you saying to use the array "A" to fill my cell array, "C(1,50)" ?

So it would be:

C(:) = {A}?

B_Richardson 2011-6-30

So I came up with this:

R = get(handles.popupmenu1,'val');

C = get(handles.listbox1,'val');

A = zeros(length(get(handles.popupmenu1,'string')),length(get(handles.listbox1,'string')));

I = sub2ind(size(A),[R repmat(R,1,length(C))],[1 C]);

Z = cell(1,50);

A(I) = 1

for i = 1: 50

Z(:) = {A}

end

The only problem is that it saves all of the listbox options and all of the popupmenu options instead of just the currently selected items.

But it does store the array A into the 1 x 50 cell array Z so I guess its a start.
