Syntax

[A] = ellipseFit(V,optMethod,numSample);

Description

Examples

n=25;
t=linspace(0,2*pi,n+1);
t=t(1:end-1);

x=2*cos(t);
y=3*sin(t);
V=[x(:) y(:) zeros(size(x(:)))]+5*randn(1,3);
V=V+0.1*randn(size(V));

Fit ellipse

% Fit ellipse
[A] = ellipseFit(V);

% Get coordinates for plotting
[VF]=ellipseCoord(A,linspace(0,2*pi,500));

cFigure;hold on;
plotV(VF,'b-','LineWidth',2);
plotV(V,'r.','MarkerSize',35);
axis equal; box on;
