Why eigen vector looks different than the calculated one

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)

v = 2×2

0.3162 -0.9487 -0.9487 -0.3162

d = 2×2

-2 0 0 8

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])

ans = 2×1

0.3162 -0.9487
