Dear group,
why these two calculations give different rezults?
In[1]:= N[
Eigensystem[{{\[Sigma]1^2, \[Rho] \[Sigma]1 \[Sigma]2}, {\[Rho] \
\[Sigma]1 \[Sigma]2, \[Sigma]2^2}} /. {\[Sigma]1 -> 1, \[Sigma]2 ->
3, \[Rho] -> 98/100}]]
Out[1]= {{9.96423, 0.0357679}, {{0.32797, 1.}, {-3.04906, 1.}}}
and
In[2]:= Eigensystem[{{\[Sigma]1^2, \[Rho] \[Sigma]1 \[Sigma]2}, {\
\[Rho] \[Sigma]1 \[Sigma]2, \[Sigma]2^2}} /.
N[{\[Sigma]1 -> 1, \[Sigma]2 -> 3, \[Rho] -> 98/100}]]
Out[2]= {{9.96423,
0.0357679}, {{0.311638, 0.950201}, {0.950201, -0.311638}}}
