Plot an ellipse in "center form"

Ellipse_plot(A,c)

This function draws an N-dimensional ellipse (N = 2,3) that is given in "center form":

(x - C)' A (x - C) <= 1

where C is the center of the ellipse, and A is an NxN positive definite symmetric matrix.

A and C could be the outputs of the function: "MinVolEllipse.m", which computes the minimum volume enclosing ellipsoid containing a set of points in an N-dimensional space. For example, you can use this function as follows:

P = rand(3,100);
t = 0.001;
[A , C] = MinVolEllipse(P, t)
figure
plot3(P(1,:),P(2,:),P(3,:),'*')
