function varargout = MainForm(varargin) % MAINFORM MATLAB code for MainForm.fig % MAINFORM, by itself, creates a new MAINFORM or raises the existing % singleton*. % H = MAINFORM returns the handle to a new MAINFORM or the handle to % the existing singleton*. % % MAINFORM('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in MAINFORM.M with the given input arguments. % % MAINFORM('Property','Value',...) creates a new MAINFORM or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before MainForm_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to MainForm_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES % Edit the above text to modify the response to help MainForm % Last Modified by GUIDE v2.5 28-Dec-2023 12:27:40 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
