Web20 nov. 2012 · Ignoring of course the nice cases θ = 0, π the rotation always does more than just rescale a vector. On the other hand, if we view the matrix as a rotation on C 2 then the eigenvectors you give show the directions in which the matrix acts as a rescaling operator in the complex space C 2. WebLet A be a 2 × 2 matrix with a complex, non-real eigenvalue λ . Then A also has the eigenvalue λ B = λ . In particular, A has distinct eigenvalues, so it is diagonalizable using the complex numbers. We often like to think of our matrices as describing transformations of R n (as opposed to C n ).
