Cara Membuat GUI MATLAB TAPIS IIR DIGITAL CASCADE-FORM DAN IMPLEMENTASINYA PADA SINYAL AUDIO








SEMUA EVENT CALLBACK GUI MATLAB:

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