MATLAB: Splitting a string of numbers and ‘|’

regexpstring

[EDIT: Tue Jun 21 20:43:11 UTC 2011 – Reformat – MKF]

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.

Best Answer

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')

How about using regexp to find the position of spaces, and delete 2nd~Nth spaces? Like:

mystring = 'this is my string';
pos = regexp(mystring,'\s');
mystring(pos(2:end)) = [];

% Prepare the Matlab listbox uicontrol
hFig = figure;
listItems = {'apple','orange','banana','lemon','cherry','pear','melon'};
hListbox = uicontrol(hFig, 'style','listbox', 'pos',[20,20,60,60], 'string',listItems);
 
% Get the listbox's underlying Java control
jScrollPane = findjobj(hListbox);
 
% We got the scrollpane container - get its actual contained listbox control
jListbox = jScrollPane.getViewport.getComponent(0);
 
% Convert to a callback-able reference handle
jListbox = handle(jListbox, 'CallbackProperties');
% Set the mouse-movement event callback
set(jListbox, 'MouseMovedCallback', {@mouseMovedCallback,hListbox});
 
% Mouse-movement callback
function mouseMovedCallback(jListbox, jEventData, hListbox)
   % Get the currently-hovered list-item
   mousePos = java.awt.Point(jEventData.getX, jEventData.getY);
   hoverIndex = jListbox.locationToIndex(mousePos) + 1;
   listValues = get(hListbox,'string');
   hoverValue = listValues{hoverIndex};
 
   % Modify the tooltip based on the hovered item
   msgStr = sprintf('<html>item #%d: <b>%s</b></html>', hoverIndex, hoverValue);
   set(hListbox, 'Tooltip',msgStr);
end  % mouseMovedCallback
