SEMUA EVENT CALLBACK GUI MATLAB:
function varargout = iir_direct_form1(varargin)
% IIR_DIRECT_FORM1 MATLAB code for iir_direct_form1.fig
% IIR_DIRECT_FORM1, by itself, creates a new IIR_DIRECT_FORM1 or raises the existing
% singleton*.
%
% H = IIR_DIRECT_FORM1 returns the handle to a new IIR_DIRECT_FORM1 or the handle to
% the existing singleton*.
%
% IIR_DIRECT_FORM1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in IIR_DIRECT_FORM1.M with the given input arguments.
%
% IIR_DIRECT_FORM1('Property','Value',...) creates a new IIR_DIRECT_FORM1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before iir_direct_form1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to iir_direct_form1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
