I have these points xy
xy = [10 -10; 1 0; -1 0; 0 -1; 0 1 ;11 -10; -1 -1];
scatter(xy(:,1),xy(:,2))
grid on
xlim([-20 20])
ylim([-15 15])
I want to mark a clusters of the data by circle. This is the function that I used incircle()
[C,R] = incircle(A(:,1),A(:,2));
viscircles(C,R,'color','b')
It does not plot proper circle around the data.
After this want to draw ellipse around all data plotEllipses
plotEllipses([0, 0], [10, 0.5])
But I dont know how to rotate ellipse
The result should be:
