说明：  计算小波能量熵，简洁明了，实测有效，只需要自己确定小波基函数与分解层数(Calculation of wavelet energy entropy)

这是小波包变换算法程序，有利于方便大家使用(This is the wavelet packet transform algorithm program will help facilitate the use of all)

能进行ofdma自适应资源分配的超好程序，本人花了很长时间琢磨出来的哦。(Adaptive resource allocation can be ofdma super good program, I took a long time figured it out, oh.)

说明：  仿真FM系统的调制解调全过程，有相干解调，非相干解调，包括大小信噪比的分析，十分完整~包含程序以及仿真结果。都是自己完成的，还有写程序中的一些问题和心得，希望对大家有帮助(The whole process of simulation FM system modulation and demodulation, coherent demodulation, non-coherent demodulation analysis, including the size of the signal-to-noise ratio, very complete to contain the program as well as the simulation results. All their completion, as well as write programs in a number of issues and experiences, we hope to help)

This model were build to simulate flicker when switches the big load to the network. The result show that, when switches the load, voltage and current fluctuate and make flicker.

Gabor filter has implemented here to find the texture boundary by varying frequency and orientation angle.

IMAGE SOURCE CODING & DECODING In This code The Coding Technique Used Is Huffman Coding Data Input Is A Gray Image The Symbols Are The Intensity Levels Of The Pixels (256 Intensity)

正则化反演的程序，可用于地球物理专业数值反演(Regularization inversion program)

将Excel里面的大量数据导入MATLAB软件里面进行画图(A large amount of data in Excel is imported into MATLAB software for drawing)

本书提供了matlab语言的编程语法和基本函数，并给出了simulink仿真实例，对于学习matlab的人来说非常有用(This book provides a matlab programming language syntax and basic functions, and gives simulink simulation for learning matlab very useful for people who)
