I cant find anything on the help for regexp that gives a way to split up numbers.

I have '1 | 2' and I need to get '1' and '2' as two separate strings.

I am getting this string from a listbox

Pos = get(handles.PositionList,'String') 
Reg_num = get(handles.PositionList,'Value')

Reg_num is so that MATLAB knows which line is selected.

str = '1 | 2';
S = regexp(str,'\d+','match')

Now S is a 1-by-2 cell array.

strcmp(S{1},'1')
strcmp(S{2},'2')

Jan Simon's method below works for mixed data strings.

Another solution:

strtrim(regexp('1 | 2', '\|', 'split'))

Pos = textscan(get(handles.PositionList,'String'), '%d', 'Delimiter', '|');
Pos{1}(get(handles.PostionList,'Value'))

Caution: If I recall correctly, I have seen cases where when you construct a listbox using '|' separated options, that the uicontrol internally converted this into a cell array of strings. It would therefore be more robust to check whether the 'String' returned was indeed ischar() or if it was iscell() instead.
