I am trying to simulate following code..
x=2;
y=2;
r=3;
ang=0:0.01:2*pi;
xp=r*cos(ang);
yp=r*sin(ang);
plot(x+xp,y+yp);
but in this code circle toch the edges..i want a circle which is in middle..how can i do it

This works:
x=2;
y=2;
r=3;
ang=0:0.01:2*pi;
xp=r*cos(ang);
yp=r*sin(ang);
plot(x+xp,y+yp);
axis([min(x+xp)-1 max(x+xp)+1 min(y+yp)-1 max(y+yp)+1])
axis square
You can use the axis function to set the limits and other properties of your figure axis.

Follow it with this:
axis([-2 6 -2 6])
axis equal
The first line sets limits of the axes, the second line ensures that the circle isn't squashed.

Try adding
margin = 2; % how much space to leave
axis([x x y y] + [-1 1 -1 1]*(r+margin));
