X = 3 + 2*randn(500,1);
Y = 2*X + 4*randn(500,1);
for this code, first I tried to find the covarience by using
CoVar= cov(X,Y)
then to find the eign values and to plot the eigen vector what do I need to do?

In order to find the eigen values, you need to have a matrix. You can plot eigen values of two matrix on a scatter plot.
A=randi(50,15,15);
B=randi(50,15,15);
eA = eig(A);
eB = eig(B);
scatter(eA,eB,'ro')
