分形，是以非整数维形式充填空间的形态特征。分形可以说是来自于一种思维上的理论存在。(Fractal, is filling in the form of non-integer dimension of space morphology. Fractal can be said to come from the existence of a theory of thinking.)

设计采用模糊控制的直接转矩控制，和传统PI调节器相比较(Design of fuzzy control of direct torque control, and compared to the traditional PI regulator)

PCA Face recognition implementation in Matlab. Simple and easy to understand

Data-Driven Robust Approximate Optimal Tracking论文的实验示例程序。(Data-Driven Robust Approximate Optimal Tracking paper experimental sample program.)

xwch_test.m是主测试文件；biaoji.mat存放滤波器系数；xiangweicha.m用FFT计算相位差。 仿真框架为： 1.标记信号和双音信号续接作为发送信号； 2.对双音中一个频率分量的相位做偏移，再经过一个低通滤波器（引入线性相位，模拟收发不能同步测量现象）后，作为收到的信号； 3.用一个检测信号对收发信号进行相关运算； 4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点，从而推算出收发双音信号0相位点； 5. 输入0相位点位置，计算相对相位差。(xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.)

说明：  数值分析newton算法的matlab实现(Numerical analysis matlab newton algorithm implementation)

ar模型检验 用于matlab中 比较简单 (ar model for matlab )

说明：  计算HURST指数，自己编写，这是经过修正之后通过变成得出来的结果，网上一般很少有这类文件。(HURST index calculation, write your own, which is revised after the results come through into a very, very few of these files online usually.)

运用matlab,采用QPSK调制与解调，包括串并转换，傅立叶变换与逆变换，信道估计（采用LS准则），多普勒频移等模块，内容清晰明了。(Use matlab, using QPSK modulation and demodulation, including string and conversion, Fourier Transform and inverse transform, channel estimation (LS criteria used), Doppler frequency shift modules, content clarity.)

用matlab编写的正交相移调制，已通过测试，可以运行(QPSK)
