copied!<p>From the result you got for the button callback, it appears that the callback has been created in the following way (just for example):</p> <pre><code>hButton = uicontrol(...,'Callback',{@button_callback,1,1,[1:6]}); </code></pre> <p>where the callback function <code>button_callback</code> is defined as follows:</p> <pre><code>function button_callback(hObject,eventdata,a,b,c) ... end </code></pre> <p>Notice that there are <a href="http://www.mathworks.com/help/matlab/creating_guis/write-callbacks-using-the-programmatic-workflow.html#brqow8p" rel="nofollow noreferrer"><em>two extra arguments</em> in the input argument list</a> for the callback function: <code>hObject</code> (the handle of the object invoking the callback) and <code>eventdata</code> (a structure of event data).</p> <p>If you want to invoke the function handle with the 3 additional arguments that should be passed to it (<code>1</code>, <code>1</code>, and a 1-by-6 array), you need to also pass arguments for the <code>hObject</code> and <code>eventdata</code> inputs. Here's how calling the function would look (using your variable <code>ans</code>):</p> <pre><code>ans{1}(hButton,[],ans{2:end}); </code></pre> <p>You first get the function handle from the cell array (<code>ans{1}</code>) then <a href="http://www.mathworks.com/help/matlab/matlab_prog/calling-a-function-using-its-handle.html" rel="nofollow noreferrer">call it using parentheses as you would any other function</a>. For <code>hObject</code> you can pass the handle to the uicontrol object (or an empty value if it isn't needed), and for <code>eventdata</code> you can just pass an empty value. The additional values are then taken from the cell array as a <a href="http://www.mathworks.com/help/matlab/matlab_prog/comma-separated-lists.html" rel="nofollow noreferrer">comma-separated list</a> (<code>ans{2:end}</code>) and each is passed to the function as a separate additional argument.</p>
