HOW TO MAKE CALCULATOR WITH MATLAB GUI

Membuat program kalkulator pada sebuah bahasa pemrograman berbasis GUI merupakan

tantangan yang menarik karena kreatifitas kita diuji dalam hal ini. Kemampuan dalam melogikakan

proses eksekusi kalkulator merupakan sedikit banyak hal yang perlu dimiliki. Saya mencoba

membuat program kalkulator dengan menggunakan matlab GUI. Silakan dipelajari dan dimodifikasi

semaunya.

berikut ini program yang bisa anda gunakan

function varargout = calculator(varargin) % CALCULATOR M-file for calculator.fig % CALCULATOR, by itself, creates a new CALCULATOR or raises the existing % singleton*. % % H = CALCULATOR returns the handle to a new CALCULATOR or the handle to % the existing singleton*. % % CALCULATOR('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in CALCULATOR.M with the given input

arguments. % % CALCULATOR('Property','Value',...) creates a new CALCULATOR or raises

the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before calculator_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to calculator_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
