To plot an ellipse you can use its equation. An ellipse has a major and a minor axis. Also we want to be able to plot the ellipse on different center points. Therefore we write a function whose inputs and outputs are:
Inputs:
r1,r2: major and minor axis respectively
C: center of the ellipse (cx,cy)
Output:
[x,y]: points on the circumference of the ellipse
You can use the following function to get the points on an ellipse and then plot those points.
function [x,y] = getEllipse(r1,r2,C)
beta = linspace(0,2*pi,100);
x = r1*cos(beta) - r2*sin(beta);
y = r1*cos(beta) + r2*sin(beta);
x = x + C(1,1);
y = y + C(1,2);
end
Exmaple:
[x,y] = getEllipse(1,0.3,[2 3]);
plot(x,y);
