How to coding fitness function.

通信系统防真，用matlab编写，ＭＣＱＰＳＫ(communication system simulation by matlab,ＭＣＱＰＳＫ)

信道化接收发射机设计，很好用。供大家一起研究学习。(Channelized receiver transmitter design, easy to use. Research for everyone to learn.)

直线电机滑模控制仿真，对直线电机滑模控制方法进行研究(Linear motor sliding mode control simulation of linear motor, sliding mode control method research)

用matlab开发的系统辩识原代码。利用最小二乘法实现辩识.(Using matlab developed the original system identification code. Realize the use of least squares identification.)

matlab代码，是在windows环境下，利用matlab r2010a开发的一段关于回归分析的代码(matlab code is in the windows environment, using matlab r2010a developed a regression analysis on the code)

说明：  里面是很多matlab的常用功能举例，matlab有很多用法不为我们所知，又因为matlab的帮助文件是英文的，看起来费劲，而这个压缩包就有很多matlab用法的举例。(Inside is many matlab commonly used function examples, matlab has many usages not to know for us, also, because the matlab help file is English, looks like uses energy, but this compression package has many matlab usage example. )

chirp信号产生比较 If you are aware of this and would still like to have a pseudo-chirp then you can take a look at the example below. I show the difference between trying to generate the type of chirp you are after and a real chirp signal. I also plot the derivative of the resulting signals, so I can highlight that between half cycles you will have a sometimes subtle (sometimes not so subtle) jump in gradient.
