用matlab画齿轮齿廓的，只要几个参数即可，具体看程序，很简单，一看就懂。(matlab build gear shape)

说明：  直方图阈值的双峰法 该阈值化方法的依据是图像的直方图， 通过对直方图进行各种分析来实现对图像的分割。(Bimodal histogram threshold method of the threshold value method is based on the histogram of the image, to achieve the image segmentation by the various analyzes of the histograms.)

Mat Lab sample file for simulation

t检验，通过多样的分析可以得出想要的熵结果。(t-test.you can download it every day.)

matlab命令汇总，里面的命令很全，基本上都是常用的命令(the matlab command summary, is the whole command inside basically used commands)

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)

用现代谱估计法中的AR模型对信号进行功率谱估计(The power spectrum of the signal is estimated by the AR model of the modern spectral estimation method)

Hand recognition using Keypoint matching algorithm is implemented

离散傅里叶变换，加窗fft解决谐波信号中的频谱泄露和栅栏效应(Discrete Fourier transform, windowed fft solve harmonic signal leakage and fence effect of spectrum)

this is the active noise developed by running an active sysetem
