MATLAB，即“矩阵实验室”，它是以矩阵为基本运算单元。从最基本的运算单元出发，介绍MATLAB的命令及其用法。(MATLAB, "Matrix lab," It was based on the matrix of the basic computing unit. Operational from the most basic unit is introduced, and MATLAB orders its use.)

利用matlba编写的遗传算法工具箱，功能强大，设置简单，运行效率高。非常好用的工具。(Matlba prepared using genetic algorithm toolbox, powerful, easy setup, operation and high efficiency. Very useful tool.)

自己写的关于粒子群算法求函数最小值的例程，简单易懂，对理解算法有很大帮助(Wrote it myself on the Particle Swarm Optimization for the minimum function of the routine, easy-to-read, to understand the algorithm are very helpful)

遗传算法的应用例子，对于初学者，有很大的帮助。谢谢(A genetic algorithm implemented in Matlab is presented Matlab is used for the following reasons:it provides many built in auxiliary functions useful for function 来源:跨考网论坛 出处地址:http://bbs.kuakao.com)

双音多频，由高频群和低频群组成，高低频群各包含4个频率。一个高频信号和一个低频信号叠加组成一个组合信号，代表一个数字。DTMF信号有16个编码。利用DTMF信令可选择呼叫相应的对讲机。(Dual tone multi-frequency, high-frequency and low-frequency group composed of groups, high-frequency group contains four frequencies each. A high-frequency signal and a low frequency signal is superimposed to form a combined signal representative of a number. DTMF signal has a 16 code. DTMF signaling to the appropriate use of the intercom call.)

无限冲击响应滤波器 (IIR) 实现，涉及一个Butterworth低通滤波器，设计指标为：在通带内频率低于0.2π时，最大衰减小于1dB；在阻带内[0.3π, π]频率区间上，最小衰减要大于15dB (An infinite impulse response filter (IIR) implementation, involves a Butterworth low-pass filter design specifications as follows: in the passband frequencies below 0.2π, the maximum attenuation is less than 1dB in the stopband [0.3π, π] frequency interval , the minimum attenuation greater than 15dB )
