here is what I have so far. I am trying to use mouse pointer to get certain values from the figure. say I have a function like this

function mouseCallback()
    h = plot(rand(10,1), 'o-');
    set(h, 'ButtonDownFcn',@mouseCall)
      function mouseCall(~,~)
          p = get(gca,'CurrentPoint');
          p = p(1,1:2);
          title( sprintf('(%g,%g)',p) )
      end
  end

the function works fine now all I want do is to call this function to get the 'p' from another function. something like

function p = mouseCallback()
.....
.....
end

the problem is when I do so execution of the function doesnot terminate as it waits for next mouse callback. Is there anyway to terminate the callback and get the value.
