Hi, I have to draw concentric ellipses (say 2) within existing ellipse...I am attaching plotted ellipse.. How can we draw that..

That is not "image processing" or "digital image processing" or even anything to do with "image", like you indicated in your Tags.

Once you know the orientation and the center and semi-major and semi-minor axes, you can construct new ellipses with the same orientation and center and using a linear scaling of the semi-major and semi-minor axes.

Sir, I am using the following function for minimum ellipsoid construction https://in.mathworks.com/matlabcentral/fileexchange/9542-minimum-volume-enclosing-ellipsoid...after that I am getting a minimum ellipsoid covering all the points...From the fucntion [A , c] = MinVolEllipse(P, tolerance)....I am getting center, how to deduce other parametrs of the current ellipse, so that we can modify radii to draw concentric ellipses...
