实现快速傅里叶变换，自编函数FFT.而不需使用matlab自带的FFT函数(it can realize the fast fuleir tansform)

wiener滤波器的matlab程序，是自己编的，希望能对大家有用(wiener filter matlab program is own the hope that it can be useful for all of us)

Keys are this set s elements. Values are always Boolean.TRUE.

降压它激推挽DC/DC的电路,输入24V直流电压，输出8V直流电压，主要起降压隔离的作用(The push-pull DC/DC circuit)

霍夫曼编码的MATLAB实现运行时需要自己添加变量值(Huffman coding to achieve run-time MATLAB need to add the variable value)

离散无记忆信源是一种最简单且最重要的信源，可以用完备的离散型概率空间来描述。本实验通过计算给定的信源的熵，加深对信源及其扩展信源的熵的概念的理解。(Discrete memoryless sources is one of the most simple and most important information source, can be used to describe a complete discrete probability space. In this study, by computing the entropy of a given source, to deepen understanding of the source and the expansion of the concept of entropy of the source. )

gm2对上下变动的数据，预测效果比gm1好，但对趋势较好的数据，预测精度没有gm1高。(gm2 on the up and down movements of the data to predict better than gm1 good, but better data on trends, forecast accuracy not gm1 high)

本程序为我自己编写的，能够实现用枚举法背包问题(This program written for my own, to achieve knapsack problem with the enumeration method)

HCS300编码。。还要最少20个字？够了吧？？(HCS300 code. . But also at least 20 words? Enough, right? ?)
