Eigenvector of Hess Matrix (Optimisation problem)












0














I am able to find eigenvalues of Hess Matrix (after plugging in the values of extreme point) but i cant find the eigenvectors of it. The row echleon form of the Matrix shows that it's a full rank matrix and therefore I cant find the basis of the kernel of the matrix (it's not empty since it still has the null vector but that's trivial solution). However, when i put in the value of Matrix in an online calculation, I still got results for the Eigenvectors but I think the row reduction steps are incorrect. When I out in the value of the Matrix in Octave, I received different results.

Would be great if someone can help me with the computation for eigenvectors of Hess Matrix... Thanks
