MATLAB, for an engineer it's an indispensable resource, extremely useful and fun to use.
But there are also some cool tricks that are rarely known and fun to implement.
1.Batman Equation Curve in MATLAB
here is a 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)) );
"
Copy paste the code to get awesome batman curve
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)
