function varargout = Filter(varargin) % FILTER M-file for Filter.fig % FILTER, by itself, creates a new FILTER or raises the existing % singleton*. % % H = FILTER returns the handle to a new FILTER or the handle to % the existing singleton*. % % FILTER('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in FILTER.M with the given input arguments. % % FILTER('Property','Value',...) creates a new FILTER or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Filter_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Filter_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 Filter % Last Modified by GUIDE v2.5 19-Dec-2020 23:10:20 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
