Why eigen vector looks different than the calculated one
显示 更早的评论
I have a matrix A = [7, 3; 3, -1]; Calculated eigen value = (-2, 8) and eigen vcetor = (1, -3). The code gives different eigen vector. Could you please clarify the reason/ how can I solve that? thanks
A = [7, 3; 3, -1];
[v, d] = eig(A)

Eigenvectors are only unique up to a multiplicative constant, and MATLAB's eigenvectors are normalized to be of norm 1:
[1;-3]/norm([1;-3])
