Question

1. Create classic animation effect using Matlab software with two examples and highlight the commands used in Matlab programming (25 Marks)

Answer 1

The MATLAB predefined function ‘comet’ can be used to display 2D animated comet plot and the function ‘comet3’ is used to display 3D animated comet plot.

Example 1:

The following is the MATLAB code that displays the animation of a ‘tan’ function using MATLAB predefined function comet:

clear all

close all

x=-2*pi:0.01:2*pi; %define vector x

y=tan(x);          %define tan as a function of x

comet(x,y)         %use comet function to display animation of function

The animation plot is shown below.

Example 2:

The following is the MATLAB code that displays the 3D animation using MATLAB predefined function comet3:

clear all

close all

x=-4*pi:0.01:4*pi;   %define vector x

y=sin(x);            %define vector y

z=cos(x);            %define vector y

comet3(x,y,z)        %use comet3 function to display 3D animation

The animation plot is shown below.
