Hi,
I draw a circle of radius 1, and I want to draw eqaully sized squares in the background of the circle. Kindly some one help,
r = 1. 0;
th = linspace(0,2*pi) ;
x = r*cos(th) ;
y = r*sin(th) ;
patch(x,y,rand(1,3)) ; % I am using random color in patch here.
axis equal
Now I want draw 10x10 squares as a background to the circle (the dia of each square is (2*r/10)).

x=[-1, 1, 1, -1, -1];
y=[-1, -1, 1, 1, -1];
plot(x, y, 'r-');
fill(x,y,'b')
hold on;
r=1.0;
th=linspace(0,2*pi) ;
x=r*cos(th) ;
y=r*sin(th) ;
patch(x,y,rand(1,3)) ; % I am using random color in patch here.

Automatically, I dont know, but manually you can do that
x1=[-1, 1, 1, -1, -1];
y1=[-1, -1, 1, 1, -1];
plot(x1, y1, 'r-');
fill(x1,y1,'b')
% one block
hold on;
x1=[-1,-0.9,-0.9,-1,-1];
y1=[-1,-1,-0.9,-0.9,-1];
plot(x1, y1, 'y-','linewidth',2);
fill(x1,y1,'r')
