The Database provides storage and retrieval of directory structure, group and individual machine policies and tasks, machine properties, IP address filters and coverage and infection event data. The Console securely connects to the server service to allow the administrator to view or change policy, view configuration and infection information, and manage groups and machines. An Agent (a component of the common framework) present on every managed system performs property collection (on the client), policy collection (from the server) and policy enforcement (at the client). The agent executes scheduled tasks, and reports any changes made to the client machine or virus incidents back to the server. The Repository, (present both on the ePO server and optionally distributed within the network of managed machines) provides a location from which managed systems can obtain products and updates. The Notification Service provides the framework on which to define rules, (based on product events), that can be used to provide real-time alerting using a variety of methods. The Rogue Sensor component detects all machines present on the network, and uses the database and preconfigured rules to determine any action required. * * * * * * * * * 线性代数 昆明理工大学 2011.1 * 第三节 相似矩阵 矩阵的相似和对角化 相关示例 一. 矩阵的相似和对角化 定义5.3.1. 设A，B为n阶矩阵，若存在可逆矩阵P，使 （1） 则称A与B相似，记作 似变换，P称为相似变换矩阵。 ，（1）式称为由A到B的相 若A相似于对角矩阵，则称A可对角化。 （2）若A与B相似，则A与B有相同的特征多项式、 特征值、秩及相等的行列式。 （3若） ，则 （m为正整数） 证明： 性质5.3.1： （1）相似概念具有如下性质： ①反身： ②对称： 若 ，则 ③传递： 若 ，则 定理5.3.1. 是A具有n个线性无关的特征向量。并且当 n阶方阵A相似于对角矩阵的充分必要条件 时，对角阵的对角元素 就是A的全部特征值，
