说明：  matlab文件结合实例，实际的优化例子，很有用的(matlab file with examples, practical optimization example, very useful)

Matlab讲义高级第5章，大家分享一下(Matlab senior notes in Chapter 5, we share)

用matlab写的可以在excle中输入变量，然后在matlab中做变量选择做一元和多元回归的程序，并可以画图表示结果。(Can write using matlab input variables in excle choose to do one yuan and multiple regression procedures, and then in matlab variables that the results and drawing.)

二次规划的matlab源代码，很有用的优化工具！(Quadratic programming matlab source code, very useful optimization tool!)

一种segy格式文件读取，用于地震资料处理，matlab文件。(One kind segy read format for seismic data processing, matlab file.)

Indexation 1-1 for image by FFT matlab

matlab与hfss的连接程序,作用为使用matlab编写Vbs脚本来控制hfss(the connection matlab code of matlab and hfss)

使用matlab，用于基于奇异值分解（SVD）的图像压缩(image compression based on Singular value decomposition (SVD))

通用卷积码的编码encoding for ALL RSC(encoding for ALL RSC)

说明：  RS的编码就是计算信息码符多项式，除以校验码生成多项式之后的余数；rs编码的基本实现，包括add,mul函数等；(RS coding is to calculate the information symbol code polynomial, divided by the check code generator polynomial after the remainder rs basically coding, including add, mul function, etc. )
