drawframe(48);
Write your drawframe function below
function drawframe(f)
x1 = [0 1 1 0];
y1 = [1 1 2 2];
x2 = [1 2 2 1];
y2 = y1;
x3 = x2;
y3 = [0 0 1 1];
for i=0:floor(f/8)
s = 2^-i;
if i==0
t = '1/4';
else
t = ['1/4^' num2str(i+1)];
end
patch(x1*s,y1*s,'b','edgecolor','k'); text(0.5*s,1.5*s,t,'horizontalalignment','center','VerticalAlignment','middle','fontsize',25/1.5^(i+1));
patch(x2*s,y2*s,'r','edgecolor','k'); text(1.5*s,1.5*s,t,'horizontalalignment','center','VerticalAlignment','middle','fontsize',25/1.5^(i+1));
patch(x3*s,y3*s,'y','edgecolor','k'); text(1.5*s,0.5*s,t,'horizontalalignment','center','VerticalAlignment','middle','fontsize',25/1.5^(i+1));
axis equal off;
end
