Hi Everybody,
I am trying to plot a circle with radius= 190 km, and the centre of circle is (2.55, 101.46)both are in degree. If I have to change in km also are become like this (283.87, 11295.0345)km. The question is how can I determine the centre of circle by symbol? and the sketch has been attached here would be useful because I do not know how to plot like this? Could you please help me?
radius = 190;
centerX = 2.55;
centerY = 101.46;
rectangle('Position',[centerX, centerY, radius, radius],...
'Curvature',[1,1],...
'FaceColor','w');
axis square;

I don't know which of the four "download" words to click on on that page. Why don't you try http://snag.gy or tinypic.com?

I don't know what "determine the centre of circle by symbol" means, but I can tell you from the code that the center of the circle is at (x, y)=(2.55, 101.46) but I don't know what you mean when you say "both are by degree". What does a pair of degrees mean? Aren't x and y in km? How are they in degrees? What does that mean?

Then perhaps you want this: http://www.mathworks.com/matlabcentral/fileexchange/34767-a-suite-of-minimal-bounding-objects? It will find the smallest circle (or rectangle or triangle, or other redefined shapes) that will contain (fit) all your points inside.
