21 Dec 2011 Ellipsoid Fitting Two matlab files to demonstrate how to fit an ellipsoid directly to a set of 3D points. Author: Q LI Toni

Why is the size of the points in the testfit (11,6)?

Should it not be 11,3 for xyz?

what is the meaning here?

where I check your test, I find the values of the major, medium and short radius from the equation u^3 - I*u^2 + J * u - K = 0 have some problems...

Here I = a + b + c
J = ab+bc+ac-f^2 - g^2 - h^2
K = |a h g; h b f; g f c|;
