Bagi yang masih bingung bagaimana membuat aplikasi kalkulator dengan GUI MATLAB brikut saya akan jelaskan langkah-langkahnya.
1. Yang pertama pastikan aplikasi Matlab terinstall di komputer
2. Yang kedua ketik guide pada command window
3. Pilih Blank gui ( Default)
4. Lalu Buat tombol kalkulator seperti gambar di atas, untuk layar hasil gunakan data stastic sedangkan untuk tombol yang lainnya gunakan push button. pastikan agar tag nya terisi agar saat memasukan sourcode tidak tertukar. misal untuk tombol 1 isi dengan tag pb1 dan seterusnya.
5. Masukan Sourcode seperti di bawah ini
function varargout = coba(varargin)
% COBA M-file for coba.fig
% COBA, by itself, creates a new COBA or raises the existing
% singleton*.
%
% H = COBA returns the handle to a new COBA or the handle to
% the existing singleton*.
%
% COBA('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in COBA.M with the given input arguments.
%
% COBA('Property','Value',...) creates a new COBA or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before coba_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to coba_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 coba

6. lalu simpan sourcode di atas.. sebelum itu coba tes kalkulator dulu
