Find eigenvectors with imaginary numbers
WebTo find the eigenvectors of a square matrix A, it is necessary to find its eigenvectors first by solving the characteristic equation A - λI = 0. Here, the values of λ represent the eigenvalues. Then by substituting each of them in the equation (A - λI) v = O and solving it for v would give the eigenvectors. Explore.

The closest I have come is one answer that suggest writing a function to strip the eigenvalues of their small imaginary parts. This works, but still leaves incorrect eigenvectors.
WebIn other words, both eigenvalues and eigenvectors come in conjugate pairs. Since it can be tedious to divide by complex numbers while row reducing, it is useful to learn the following trick, which works equally well for matrices with real entries. Eigenvector Trick for 2 × 2 Matrices. Let A be a 2 × 2 matrix, and let λ be a (real or complex ... WebMay 12, 2013 · The eigenvalues returned by scipy.linalg.eig are not real. Some of the eigenvalues are negative. Both of these issues are the result of errors introduced by truncation and rounding errors, which always happen with iterative algorithms using floating-point arithmetic. Note that the Matlab results also produced negative eigenvalues.
