Flower using Rotational Matrix in MATLAB Program

MATLAB Program: 

Code:

figure;

pause(5);

fill([-10 -10 10 10],[-10 10 10 -10],'k');

hold on;

pause(1);

t=0:0.01:pi;

x=0.5*sin(t);

plot(t,x,'w','linewidth',2);

hold on;

for i=1:10

q=[t;x];

e=pi/4*i;

z=[cos(e) -sin(e);sin(e) cos(e)];

k=z*q;

r=k(1,:);

d=k(2,:);

plot(r,d,'w','linewidth',2);

pause(0.5);

axis equal;

end

t=0:0.01:pi;

x=-0.5*sin(t);

plot(t,x,'w','linewidth',2);

hold on;

for i=1:10
