% INTERFACE3, by itself, creates a new INTERFACE3 or raises the existing
% singleton*.
% H = INTERFACE3 returns the handle to a new INTERFACE3 or the handle to
% the existing singleton*.
% INTERFACE3(‘CALLBACK’,hObject,eventData,handles,…) calls the local
% function named CALLBACK in INTERFACE3.M with the given input arguments.
% INTERFACE3(‘Property’,‘Value’,…) creates a new INTERFACE3 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before interface3_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to interface3_OpeningFcn via varargin.
% *See GUI Options on GUIDE’s Tools menu. Choose “GUI allows only one
% instance to run (singleton)”.

ربنا يوفقك إلى الحل يا أخي … و لكن رأيي إنك تحاول تنسق البرنامج في شكل أحسن من كده علشان يكون سهل إن إخواننا يقدروا يفهموه لأنه طويل … أقترح عليك إنك تكتبه أولا على أى برنامج كتابة نصوص مثل ال word و بعذ ذلك ضعه في المرفقات
