Eigenvectors in mathematica
WebOct 24, 2012 · while Mathematica yields: EigVec = 0.2833 -1.2833 1 0.6417 -0.1417 -2 1 1 1 From the Matlab documentation: "For eig (A), the eigenvectors are scaled so that the norm of each is 1.0.". Mathematica on the other hand is clearly scaling the eigenvectors so that so the final element is unity. WebJun 20, 2024 · The Definition of an Eigenvector X is some vector X that satisfies AX = kX where A is a matrix and k is a constant. It is pretty clear from the definition that cX is also an Eigenvector for any c not equal to 0. So there is some constant c such that X_matlab = cX_mathematica.
