Diagonalisation theorem
Web8.2 Orthogonal Diagonalization Recall (Theorem 5.5.3) that an n×n matrix A is diagonalizable if and only if it has n linearly independent eigenvectors. Moreover, the … 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.
