Matlab: Circle Plotting Error
I have a matlab program. In that program I do not know the function for plotting a circle. Whether it is fplot, ez plot, funplot. Can any body guide me?
clc, clear all, clf,close
a = input('Give the centre X coord : '); % X coord of centre
b = input('Give the centre Y coord : '); % Y coord of centre
r = input('Give the radius of circle : '); % Radius of the circle to be drawn
inc = input('Give the increment step for coordinate[Default:1]: '); % Use the value
if isempty(inc) % of inc greater than 1
inc =1; % usually less than radius
end
x = 0;
y = r;
d= 3-2*r;
while(x < y)
plot(a,b,x,y,r);
if d>=0
d = d +4*(x-y)+10;
x = x + 1/inc;
y = y - 1/inc;
else
d = d + 4*x +6;
x = x+1/inc;
end
end
plot(a,b,p,q,r)
for i= -1:2:1
for j= -1:2:1
plot(a+i*p,b+j*q,'r.');
plot(a+i*q,b+j*p,'r.');
grid off
hold on
end
end
title('Bresenham circle')
axis([a-r-1 a+r+1 b-r-1 b+r+1])
axis equal;
0
