URGENT help for matlab GUI !!!

URGENT help for matlab GUI !!!

URGENT help for matlab GUI !!!

(OP)
Hi everybody,
I am a new one here and i need your help. I need to know what is wrong with the program i am writing on Matlab 6.
Its GUI form for solving differential equations and visualization of the results. I am using radiobuttons for switching the solvers but something is wrong with ode functions and i cant help it by myself.
Thank you,
Here is the code:

function varargout = Visualization(varargin)
% VISUALIZATION M-file for Visualization.fig
%      VISUALIZATION, by itself, creates a new VISUALIZATION or raises the existing
%      singleton*.
%
%      H = VISUALIZATION returns the handle to a new VISUALIZATION or the handle to
%      the existing singleton*.
%
%      VISUALIZATION('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in VISUALIZATION.M with the given input arguments.
%
%      VISUALIZATION('Property','Value',...) creates a new VISUALIZATION or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Visualization_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Visualization_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
%
