WebMay 4, 2024 · Since the matrix is defective, you need a generalized eigenvector. Once you have both, you need to find the Jordan form, which basically says how A acts on its one true eigenvector (multiplies it by − 2) and how it acts on the generalized eigenvector (which will be to multiply it by − 2 and then add the other eigenvector). Web183 1 1 5. matrix will be eigenvalues of the larger matrix. You need only extend the eigenvector by two zeros and you have an eigenvector of the new matrix. –. Mar 7, 2013 at 13:43. The way that we could preserve the eigenvalues is to conjugate the matrix. As switching basis means conjugating its linear transformation. proof of posting sheet
