Thanks Anton,

what function in Eigen, that you're using to get the eigenvector?   Matrix3d Eigenvectors = A.eigenvectors() doesn't work (A is a 3x3 matrx)...


Yours,

That's true. That is one of reasons, why we move to Eigen library.
Just wait a little bit, we have almost finished. (Or I am too optimistic ;) )______________________________

Hi,

Wm3 was not able to carry out eigendecomposition correctly on my matrix, and gave "NaN".   Eigen tuxfamily, on the other hand, does not have spectral/eigen decomposition.  Does anyone know what's wrong with the eigendecomposition in Wm3?




Yours,

Boon
