This website uses cookies to ensure you get the best experience. image/svg+xml. So lambda is an eigenvalue of A. To find eigenvectors, take $ M $ a square matrix of size $ n $ and $ \lambda_i $ its eigenvalues. Just type matrix elements and click the button. The second printed matrix below it is v, whose columns are the eigenvectors corresponding to the eigenvalues in w. Meaning, to the w[i] eigenvalue, the corresponding eigenvector is the v[:,i] column in matrix v. In NumPy, the i th column vector of a matrix v is extracted as v[:,i] So, the eigenvalue w[0] goes with v[:,0] w[1] goes with v[:,1] We figured out the eigenvalues for a 2 by 2 matrix, so let's see if we can figure out the eigenvalues for a 3 by 3 matrix.
