Help regarding functions and variables

I am creating a GUI and writing a script to simulate the random packing of carbon fibers. So the required output that I would be concerned is the graphic from the GUI itself. I am having problems calling a function that has variable argument outputs and variable argument inputs.This function needs to be called when I click on a pushbutton. Also, I have created a handle that stores the value of the pushbutton. I am having problems accessing the data in this handle like the value,string etc. Any kind of help would be appreciated. For your reference, these are the error messages I get.
Error in samplerandom1>pushbutton1_Callback (line 80)
if strcmp(handles.st,Start)
Error in gui_mainfcn (line 96) feval(varargin{:});
Error in samplerandom1 (line 42) gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)samplerandom1('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback
I would like to know what these errors mean and how could they be solved.
Thanks in advance.

Hi,
it looks as if you want to compare the string value? In this case you need to retrieve it first, so
if strcmp(get(handles.st, 'string'), Start)
and in case that you mean the string Start instead of the value of a variable Start:
if strcmp(get(handles.st, 'string'), 'Start')

Hi, for this I would take a look at the documentation that describes this much better than I could do this ;-).
