给出了(2,1,3)卷积编码和维特比译码的源程序(Given (2,1,3) convolutional coding and Viterbi decoding of the source)

MATLAB编写的用于属性约简的程序,先运行ROUGH.MDF文件,再输入RED,就可得到约简后的规则.(MATLAB prepared for the attribute reduction procedures, first running ROUGH.MDF documents, admission RED, can be about the simple rules.)

基于otsu算法的图像分割算法实现，经过多次验证，程序无错误。(Based on Otsu algorithm for image segmentation algorithm, after repeated verification, error-free program.)

用matlab实现对语音信号的短时分析，包括清音和浊音的判决，基音周期的估计，实验报告。(Implemented by matlab short time speech signal analysis, including the voiceless and voiced judgments, estimates, lab reports pitch period.)

这是简易的FSK信号调制，把文件放入matlab的文件库中，通过在matlab的命令窗口直接调用功能函数并运行，可以直接看到仿真结果。(This is a simple FSK signal modulation, the file into Matlab file library, call function directly in the Matlab command window and run the simulation results can be seen directly.)

用VITEBI算法对信道输出解码。这个算法既能用于卷积码的软判决解码，也能用于硬判决解码(failed to translate)

对于想要学习matlab应用的朋友，能从这份国外计算机科学经典教材之MATLAB科学计算中获得启发。(For those who want to learn matlab application friend from abroad this MATLAB scientific computing in computer science inspired by the classic textbook.)

说明：  几种用于阵列信号处理的常见函数，附带有详细的编程步骤与方法！(Several commonly used in array signal processing functions, with a detailed programming steps and methods!)
