说明：  RBF(径向基神经网络)用于预测，本文讲解几种RBF神经网络。(RBF (RBF neural network) is used to predict, the paper explains several RBF neural network.)

遗传算法，基因突变函数，交叉函数，二进制转十进制，十进制转二进制(Genetic algorithms, function mutation, crossover function, binary to decimal, decimal to binary)

三级倒立摆的非线性部分采用S函数实现，此为S函数实现的源代码(The nonlinear part of the triple inverted pendulum using S functions to achieve, this is the S function, the source code)

该模型是一个模拟信号数字化传输系统，该模型只通过了PCM编码模块和译码模块(The model is an analog signal digital transmission system, the model only through the PCM coding and decoding module module)

球粒子Mie散射（含蒙特卡洛仿真）The ball particles Mie scattering(The ball particles Mie scattering (including Monte Carlo simulation))

POS粒子群算子，用MATLAB实现其编程，文档里面有具体的介绍，算法的来源，优点，应用，还有一些列子(POS particle swarm operator, MATLAB programming, there is a specific document is introduced, the source of the algorithm, advantages, applications, and some example)

利用firpmord和firpm函数设计双带通滤波器，其指标为，第一带通指标：f =4kHz,f =5 kHz ,f =3.6 kHz ,f =5.4 kHz 第二带通指标：f =6kHz,f =7 kHz ,f =5.6 kHz ,f =7.4 kHz 通带衰耗A <3dB，阻带衰耗A >40dB，抽样频率f =20kHz。(Double belt pass filter using firpmord and firpm function design, for its indicators, through the first area index: f = 4 kHz, f = 5 kHz, f = 3.6 kHz, f = 5.4 kHz The second bandpass indicators: f = 6 kHz, f = 7 kHz, f = 5.6 kHz, f = 7.4 kHz Pass band attenuation A < 3 db, stop-band attenuation A > 40 db, f = 20 KHZ sampling frequency.)

自相关虽然能够判断清/浊音，并估计浊音的基音周期，但是其运算量很大，用乘法运算所需时间较长。为了避免乘法，采用短时平均幅度差函数（AMDF），验证AMDF与自相关有类似的作用，即平均幅度差函数能够代替自相关函数进行语音分析。(Although autocorrelation can differ from the Voiced/Unvoiced and voiced the pitch period estimate, but the operation is large enough, with the multiplication time was needed. In order to avoid the multiplication using the short time average magnitude difference function (AMDF), verify the AMDF and autocorrelation have a similar effect, that the average magnitude difference function can replace the voice of the autocorrelation function.)
