此为基于二代提升小波的阈值压缩算法源码，其中可以设置小波变换的分解层数，使用的小波名称，及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制，方便在其上进一步压缩，如采用Huffman压缩等，程序思路清楚，附有完整的注释，可以使用多种小波，并且很好得体现了二代小波的思想，对于初学小波者帮助很大。(based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.)

利用matlab实现功率谱估计中的间接法，不是通过函数调用实现的，是根据算法的思想，一步一步实现的，文件夹中还有实现自相关的算法(Using matlab to achieve the indirect method of power spectrum estimation, not by function calls, is based on the idea of ​ ​ the algorithm, step by step, the folder also auto-correlation algorithm)

在立体空间中绘制八面体的Matlab源程序，并对该八面体进行分类(Draw octahedral Matlab source in three-dimensional space and classify the octahedral)

用于对ABAQUS的INP文件进行修改 能够实现基于节点坐标变化的网格的重新划分(ABAQUS is used to modify the INP file to node-based grid coordinates of the re-classification change)

C-C方法用来计算时间延迟和时间窗口，适用于混沌时间序列，在求混沌时间序列的相空间重构时，用来计算时间延迟。(The C-C method is used to calculate the time delay and time window,it is suitable for chaotic time series, when you restructure the phase space reconstruction for chaotic time series, you can used it to calculate the time delay.)

模糊控制的Matlab仿真，跟踪的信号时方波信号(Fuzzy Control Matlab simulation tracking signal square wave signal)

该文件包含158个在MIMO-OFDM中常用的matlab函数，应有尽有。有了他就不用再看别的。(The file contains 158 commonly used in MIMO-OFDM matlab function, everything. With him would not look at anything else.)

说明：  使用人工势场法APF完成机器人的避障及路径规划(Using APF to complete obstacle avoidance and path planning of robot)

1．产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通， 低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。 2.采集一段含有噪音的语音信号（可以录制含有噪音的信号，或者录制语音后再加进噪音信号），对其进行 采样和频谱分析，根据分析结果设计出一合适的滤波器滤除噪音信号(1. Produce a continuous signal, including low-frequency, medium frequency, high-frequency components, its sampling, spectral analysis, are designed for three high-pass, low pass, band-pass filter the signal filtering treatment to observe the signal spectrum after filtering. 2. Acquisition section of the speech signal contains noise (can record a signal containing noise, or voice recording, additional noise after the signal), its sampling and spectral analysis, based on an analysis of the results to design a suitable filter to filter out one noise signal)
