Diagonalisation theorem
WebPreface. A square n × n matrix A is called diagonalizable if it has n linearly independent eigenvectors. For such matrices, there exists a nonsingular (meaning its determinant is not zero) matrix S such that S − 1AS = Λ, the diagonal matrix. Then we can define a function of diagonalizable matrix A as f(A) = Sf(Λ)S − 1. WebThe block diagonalization theorem is proved in the same way as the diagonalization theorem in Section 5.4 and the rotation-scaling theorem. It is best understood in the case of 3 × 3 matrices. Block Diagonalization of a 3 × 3 Matrix with a Complex Eigenvalue. Let A be a 3 × 3 matrix with a complex eigenvalue λ 1.
