Compendium of PDE using MATLAB

MFCC,即倒谱系数，也是语音的一个特征之一，能够充分利用人耳的特性 ％ 具体的求法就是预处理，然后加窗，进行傅立叶变换，再求出功率普 ％ 然后得出其自然对数，最后进行dct变换 ％ 代码是用matlab写的，用到的一个语音工具箱，可以从网络上下载。(MFCC, that is, just a few pedigree, as well as a voice of one, to take full advantage of people's ears% of the specific characteristics of the solution is pretreatment, then increasing the window, Fourier transform, another sought power pu% then come to its natural logarithm, culminating transform% Extra code is written in Matlab. use of a voice box can be downloaded from the Internet.)

Embedded Zero tree algorithm......... used for compression...significant positive , significant negative, isolated zero, zero tree

说明：  OPTICS Learning by Computing, with Examples Using Mathcad, Matlab, Mathematica, and Maple

ARIMA与RBF复合模型在设备运行状态趋势预测中的应用(ARIMA and RBF complex model equipment running trend prediction)

说明：  noma的固定算法和树形算法的matlab仿真，可以直接运行。(Matlab simulation of fixed algorithm and tree algorithm of noma can run directly.)

这是一部分关于RBF的论文，对股市预测很油帮助(This is part of the paper on the RBF, the stock market is the oil to help predict)

说明：  二相相移键控（BPSK）是用二进制基带信号（0、1）对载波进行二相调制。BPSK是最简单的PSK形式，相移大小为 180°，又可称为2-PSK。在群点聚集的地方，其实都不是非常有关系，在该图像中，群点分布在水平轴上的0°和180°上。由于BPSK使用严重的失真致使解调器作出错误的判断，所以该调制方式是所有PSK中最强的。但它只能以1bit/symbol调制而不适合高数据率应用情况。 (bpsk modulation)
