7 most awesome matlab tricks - Bet you don't know

 

MATLAB is a multi-paradigm numerical computing environment and proprietary programming language developed by MathWorks

1.Batman Equation Curve in MATLAB

Source Code:

 "xr = linspace(-7,7,1500);

yr = linspace(4.5,-4.5,1500);

x = repmat( xr , [ numel(yr) 1 ] );
y = repmat( yr' , [ 1 numel(xr) ] );

batman = (((x/7).^2.*sqrt(abs(abs(x)-3)./(abs(x)-3))+((y/3).^2) .*  ...
           sqrt(abs(y+(3*sqrt(33)/7))./(y+(3*sqrt(33)/7))))-1) .* ...
         (abs(x/2)-((3*sqrt(33)-7)/112).*(x.^2)-3+sqrt(1-(abs(abs(x)-2)-1).^2) - y) .* ...
         (9*sqrt(abs((abs(x)-1).*(abs(x)-0.75))./((1-abs(x)) .* (abs(x)-0.75)))-8*abs(x)-y) .* ...
         (3*abs(x)+0.75*sqrt(abs((abs(x)-0.75).*(abs(x)-0.5))./((0.75-abs(x)).*(abs(x)-0.5)))-y) .* ...
         (2.25*sqrt(abs((x-0.5).*(x+0.5))./((0.5-x).*(0.5+x)))-y) .* ...
         (((6*sqrt(10))/7)+(1.5-0.5*abs(x)) .* sqrt(abs(abs(x)-1)./(abs(x)-1))-((6*sqrt(10))/14).*sqrt(4-(abs(x)-1).^2)-y);

imagesc( log(abs(batman)) );

2.Super Mario Brother Theme

Access this feature  using this file

"http://www.mathworks.com/matlabcentral/fileexchange/8442-theme-from-super-mario-brothers-song?download=true"

Keep these two files in the same folder and run "mariosong.m" , it Will play the ultra cool super mario music.

3.SPY

Put the "SPY" command in command window, it will create a spy image like this :-

4.TOILET COMMAND :P

Enter the "TOILET" command, it will show the simulation of toilet with flushing sound :D :P

5.The Conway's Game of Life

Yes, MATLAB  can also be used to play games,enter the Life command and play.

6.The PENNY

This gives a 3D version of a penny.

Just enter  "penny" command

7. MATLAB PROGRESS BAR

Copy -paste this code to get a progress bar

clc;
clear all;
tic;
disp ('Hello, World!');
h=waitbar(0,'Please wait..');
n=0;
for i=1:100
    waitbar(i/100)
    for j=1:100
        for k=0:100;
            n=factorial(2);
        end
    end
end
close(h)
