基于Matlab的带通滤波器的设计源码，可以通过此代码，模拟带通滤波器的设计。并附有仿真后的图像。(Matlab-based band-pass filter design source, through this code, analog band-pass filter design. Together with simulation, the image.)

The files included implement the M3 Enigma machine. Rotors.m implements the GUI and enigma.m implements the cipher substitutions. The implementation can be used as an aid to teaching the enigma machine. Also, the source can be used to show how to implement an enigma machine. The files are thoroughly commented and the application can run in MATLAB by just typing rotors

说明：  matlab编写的训练som神经网络源程序 (Matlab prepared by the neural network training som source)

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

一本数学手册，对于论文中的公式推导和性能分析有一定的帮助。(A mathematical reference books, for formula deduction and performance analysis is very helpful)

说明：  1/3倍频程分析。有需要做这方面研究的同志们可以好好看一下。(1/3 octave analysis. There is a need to do research in this area can be a good look comrades.)

说明：  这是一个VC++和MATLAB联合环境下的编程,很有用的,MATLAB的数据显示很强大的,希望对你们有用.(This is a example used combation of vc++ and matlab ,because the vistual of data is very strong ,I hope it will benefit to your.)

说明：  Simulation based on age verification

典型的信号以及matlab实现，适用于初学者，里面有正余弦信号等基本信号。(A typical realization of the signal and matlab for beginners, there are sine and cosine signals and other basic signal.)

假设有一组海底深度测量数据，采用插值方式绘制海底形状图。(Assuming that there is a group of undersea depth of measurement data, using interpolation methods seabed mapping the shape of Fig.)
