WebAs a rule of thumb, over C almost every matrix is diagonalizable. More precisely: the set of complex n-by-n ... In general, a rotation matrix is not diagonalizable over the reals, but all rotation matrices are diagonalizable over the complex field. Some matrices are not diagonalizable over any field, most notably nonzero nilpotent matrices ... WebNon-diagonalizable means that there is some Jordan block of size greater than 1. I decided to hunt for something with Jordan form ( 0 1 0 0). So I want trace and determinant to be zero, but the matrix not to be zero. The diagonal entries made sure the trace vanished, and then the off diagonal entries were forced. Share. Cite. Improve this answer.

WebOf course the correct answer to the main question is ``No'' because of the phenomenon of nilpotent matrices. A matrix such as has 0 as its only eigenvalue but it is not the zero matrix and thus it cannot be diagonalisable. It is clear that if N is nilpotent matrix (i. e. Nk = 0 for some k) then it is diagonalisable if and only N = 0. WebRecall the deﬁnition of a unitarily diagonalizable matrix: A matrix A ∈Mn is called unitarily diagonalizable if there is a unitary matrix U for which U∗AU is diagonal. A simple consequence of this is that if U∗AU = D (where D = diagonal and U = unitary), then AU = UD and hence A has n orthonormal eigenvectors. This is just a part of the
