storing a value as a vector

Hello,

I am running an iteration which helps find the eigenvalues of a matrix. I want to store the eigenvalues in each iteration so that I can analyze them later. What should I use ? I don't know why

B(:,:) = eig(A)

doesn't work. There are four eigenvalues expected in one matrix.

for ii = 1:N
 B(:,n) = eig(A);
end
