how to get coordinates of a marker

How can I get the x and y coordinates of the points on the circle. the center of the circle is at (346,278). I ploted the circle using the following command.

plot(346,278,'Marker','o','color','k','Markersize',20).

Thank you for your help

Already you have the coordinates in hand right?

(346, 278)

this one is the ceneter of the circle. I want the coordinate values on the circle. The circle is not ploted using inhand data. the circle can be ploted using 'marker size' command of matlab, given its center.

You can plot your required circle given center and radius using the below method.

C = [346 278] ;  % Center of the circle 
R = 0.5 ;   % Radius 
th = linspace(0,2*pi) ; 
x = C(1)+R*cos(th) ; 
y = C(2)+R*sin(th) ;
