求解TSP问题，即在N个城市中各经历一次回到出发点，使所经过的路程最短。采用连续的Hopfield网络实现以5个城市为例的TSP问题。(TSP problem, that each of the N cities experiencing a return to the starting point, so that the shortest distance elapsed. Use continuous Hopfield networks to five cities as an example of the TSP.)

it consists of matlab code for vehicle routing problem with time windows using Tabu search

对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)

说明：  根据滤波器指标选择合适的窗函数，计算窗函数的长度N，调用MATLAB函数fir1设计一个FIR低通滤波器。并编写程序，调用MATLAB快速卷积函数fftfilt实现对xt的滤波。绘图显示滤波器的频响特性曲线、滤波器输出信号的幅频特性图和时域波形图。  (Select the appropriate indicators according to filter window function, calculate the length of window function N, called MATLAB function fir1 design a FIR low-pass filter. And programming, call MATLAB functions fftfilt achieve fast convolution filtering xt. Graphics filter frequency response curve, the filter output signal amplitude and frequency characteristics of maps and time-domain waveform.  )
