WebThough A isnot diagonalizable in the classic sense, we can still simplify it by introducing a term called "block-diagonal" matrix. Example 13.2. For the matrix A in(1) above that has complex eigenvalues, we proceed to choose P and D as follows: pick one complex eigenvalue and its eigenvector ‚0=i; ~u = · 1 ¡i ¸ = · 1 0 ¸ ¡i · 0 1 ¸ WebThe simple final result is. where the powers of a diagonal matrix are evaluated as powers of the eigenvalues along the diagonal. For any function expressible as a power series one then has. Apply this to the 2×2 Hermitian matrix. The eigenvalues are and the corresponding normalized eigenvectors are. The diagonalizing matrix and its inverse are.
