function varargout = ayunda(varargin)

% AYUNDA MATLAB code for ayunda.fig

%      AYUNDA, by itself, creates a new AYUNDA or raises the existing

%      singleton*.

%

%      H = AYUNDA returns the handle to a new AYUNDA or the handle to

%      the existing singleton*.

%

%      AYUNDA('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in AYUNDA.M with the given input arguments.

%

%      AYUNDA('Property','Value',...) creates a new AYUNDA or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before ayunda_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to ayunda_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".

Fungsi-fungsi dalam visualisasi data 3D

Mesh fungsi yang digunakan dalam memvisualisasikan data dalam bentuk permukaan tiga dimensi disebut fungsi mesh. Fungsi ini sering disebut sebagai grafik jala yang terdapat empat titik data terdekat dalam ruang 3D.

Surf sering disebut sebagai grafik permukaan.Fungsi ini digunakan untuk memvisualisasikan data dalam bentuk permukaan 3D dengan pewarnaannya berdasarkanbobot nilai grid. 

Contour ini digunakan untuk membuat gariskontur dari data 3D. Garis-garis kontur ini dibuat denganteknik interpolasi dari titik-titik terdekat.
