说明：  matlab建模与仿真带源码于群版，亲测非常全面，带书中例子和simpower使用手册(Matlab modeling and simulation)

机器学习的实践书，图灵程序设计用书。有需要的可以学习一下(Practice book of machine learning)

子类方法不可比父类方法抛出更多的例外。子类抛出的例外或者与父类抛出的例外一致，或者是父类抛出例外的子类型。或者子类型不抛出例外。(Class methods are not comparable to the parent class method throws more exceptions. The subclass thrown exception or thrown with the parent class exceptions, or the parent class throw exception sub type. Do not throw exceptions or sub type. )

说明：  主用用于通信中的MAC层协议的仿真，模拟节点发包、丢包过程(For the simulation of communicate system)

In this article an attempt has been made to solve load frequency control (LFC) problem in an inter- connected power system network equipped with classical PI/PID controller using grey wolf optimization (GWO) technique. Initially, proposed algorithm is used for two-area interconnected non-reheat thermal- thermal power system and then the study is extended to three other realistic power systems, viz. (i) two- area multi-units hydro-thermal, (ii) two-area multi-sources power system having thermal, hydro and gas

说明：  本手册提供规划安装、安装、调试、使用和维修传动所需的信息(This manual provides information needed for planning installation, installation, commissioning, use and maintenance of the transmission)

this is a book on nine free programs every pc should have.
