[WM]: Question on associate eigenvectors

[deepthi reddy <deep_269@yahoo.co.in>]

Hello everyone,
 
Iam new to this field. Iam present working on a paper on robust digital watermarking, and i encountered this problem while
normalising the image.
 
there is a 2 by 2 matrix M. what the paper says exactly is " take its associate eigenvectors [e1x e1y] "
 
using the following command in matlab:-
[v d]=eig(M) , i got a 2 by 2 matrix for v. 
can someone tell me what [e1x e1y] would be?
 
deepthi
