The purpose of this paper is to study the perturbation of special matrix eigenvalues.Using the schur triangular factorization of matrix and the theorem of Wielandt-Hoffman,we obtain the absolute perturbation bounds of diagonalizable matrix.We get the results,which extend the corresponding results of symmetrizable matrix and the theorem of Wielandt-Hoffman.
