Was wondering if anyone could help, i am trying to work out eigenvectors after working out the 3 eigenvalues for the below matrix:
[5 3 2
1 4 6
9 7 3]
My eigenvectors are correct however for 2 of the eigenvalues, my eigenvectors have opposite signs.
I have checked these in MathCAD so i know that the eigenvectors are correct however for some reason some of the signs are opposite.
I have attached my workings for the eigenvalue 1.65, the eigenvectors shown have opposite signs, can anyone spot why.
Thanks so much for your help.
