File Information
Description

NDellipse returns 2d coordinates of several ellipsoids defined by NDslices.

Usage [x , y] = ndellipse(M , S ,[H] , [R] , [N]);
 
Inputs
------
 
     M : Mean vector (d x 1 x [n1] , ... , [nl])
     S : Covariance (d x d x [n1] , ... , [nl])
     H : Transfert Matrix (2 x d) (default H = eye(2 , d))
     R : Such that y'Sy < R (default R = 2.44774683 = sqrt(chi2inv(0.95 , 2)))
     N : Number of points to draw ellipsoids (default N = 50)
 
 
 Outputs
 -------
 
    x : x-coordinate (1 x N x [n1] , ... , [nl])
    y : y-coordinate (1 x N x [n1] , ... , [nl])
