MATLAB: How can i create a circle around a point in the 2 D plane with a specified radius and determine its interscection piont with another circle

circleintersectionplotpointradius

Hi people,

i have given point , lets say (x,y)=(3,5) and would like to draw a circle around it with radius r=2. I searched for a routine in matlab but didnt find one.

My aim is to finally plot various circles and to determine the intersection points.

I hope you can help me,

With best regards, John

If you know Radius and center of circle, you can draw using:

R = 2. ;  % say R is 2 
C = [0. 0.] ;   % Let center be origin 
th = linspace(0,2*pi) ; 
x = R*cos(th) ; y = R*sin(th) ; 
xc = C(1)+x ;
yc = C(2)+y ;
plot(xc,yc) ;

As you know Radius, you can follow the above steps.

If you want to shift the center, from the circle coordinates, subtract the center, the circle will be centered at origin.

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?
