Hi everyone,

My question is concerning the discontinuity of the eigenvectors !!!

Firstly, using Eigen Library c++, I calculated the Eigen vectors of complex square matrices for 201 frequencies, for each frequency I have a square complex matrix 3 * 3 that I have to calculate its Eigen vectors.

I made the same calculations using matlab

The values obtained by Matlab are different from those obtained by c ++. I know that we can find several Eigen vectors but the problem is as follows :

I tried to compare the vectors obtained by matlab and obtained by c ++ graphically, I traced the magnitude of the components of each Eigen vector for the 201 matrices but I noticed a weird thing, the Eigen vect of matlab are continuous but the Eigen vect of c ++ are discontinuous!

can someone explain to me why please !!

Thank you
