MATLAB: Need a script to plot a circle with given radius and center

Question

I need some help guys! Need a script to plot a circle with center(5,7) and radius 3. I have these:

clear clc
  r=3;
   t=0:pi/24:2*pi;
  x=r*cos(t);
  y=r*sin(t);
   plot(x,y,x,y)
   grid on

But only the radius works.. help please.

See the FAQ for code examples: http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F

Here's one way from the FAQ that is most similar to yours:

xCenter = 5;
yCenter = 7;
theta = 0 : 0.01 : 2*pi;
radius = 3;
x = radius * cos(theta) + xCenter;
y = radius * sin(theta) + yCenter;
plot(x, y);
axis square;
xlim([0 10]);
ylim([0 12]);
grid on;
axis equal;
