软解调程序，可用于各个通信系统的软解调，(softdemodulation)

说明：  换热器模型的MATLAB实现，可用于工程计算，还可以用于教学演示(exchanger MATLAB model can be used for engineering calculations, can also be used for teaching demonstration)

实现功能 1) 在用户界面设置录音时长并实时录音 2) 调节放音幅度、播放原声并进行时域、频域绘图 3) 对收集的声音进行倒放处理并播放 4) 对收集声音进行回声处理并播放，比对时域波形 5) 对收集声音进行回响处理并播放，比对时域波形 6) 对经过回声处理的声音进行回音消除并比对时域波形 7) 采用自适应滤波器消除采集声音中的环境噪音 8) 设计相应的滤波器组成均衡器对收集的声音进行处理并播放 9) 男女声识别 10) 设计参数可调的滤波器对采集的声音进行处理 (1) in the user interface to set the recording length and real-time recording 2) to adjust sound, played acoustic amplitude and time domain, frequency domain mapping 3) to upend the collection of sound and play 4) to collect sound echo processing and playback, than in the time domain waveform 5) to collect sound echoes, processing and playback, than in the time domain waveform 6) to echo and treated with echo s voice than in the time domain waveform 7) using adaptive filter to eliminate ambient noise in acquisition voice 8) to design the corresponding filter to process the voice of equalizer to collect and display 9) NanNvSheng recognition 10) tunable filter design parameters for voice processing )

由西安电子可以大学雷英杰老师编写的第一本关于遗传算法matlab工具箱的专著，使用的是英国谢菲尔德大学的版本工具箱，很有参考价值，需要的快下载。(From Xidian University, LEI Ying-jie teachers can be prepared in the first book on genetic algorithm matlab toolbox monographs, using a version of the University of Sheffield toolbox, a good reference value, the need for faster download.)

核主成分分析方法是主成分分析的改进算法，其采用非线性方法提取主成分(Kernel principal component analysis method is an improved algorithm of principal component analysis, which uses a nonlinear principal components extracted)

Simply interpretation of Tsiolkovski equation for students

This is a simple a gorithm for fingerprint image thinning. The image should be of good quality and binarized prior to the thinning. The thinning process is by using morphological mathematics.

说明：  遗传算法分程序 选择交叉变异源程序 谢谢大家(GA selection crossover mutation )

非负矩阵分解的一种新方法——Nesterov法，这种方法提出不久，实现的结果很不错(NMF is a new method--Nesterov method, this method is presented shortly to achieve very good results)
