Hi, I have a covariance matrix and i can compute the eigen values and eigen vectors. but from these information, i am unable to formulate an ellipse. I am unable to calculate the orientation of the ellipse.Can any one help me in it and point out any good source of information for calculating the the orientation of ellipse.
Thanks

Don't the eigenvectors themselves already define the orientation of the ellipse? If not, what does?

I think the major axis corresponds to the minimum eigenvalue, and the better way to compute the angle would be
atan2(V(2),V(1))
