SECTION 5.3 DIAGONALIZATION EXAMPLE. Use the factorization A = PDP - 1 shown below to ﬁnd a simple formula for A k , where k is an arbitrary positive integer. Then discuss what happens to A k as k → ∞ .

Which matrices are diagonalizable?

A p × p matrix A is diagonalizable exactly when A has p linearly independent eigenvectors. It turns out that the dimension of the eigenspace for an eigenvalue is less than or equal to
