Affine-invariant

说明：  基于MATLAB的直接序列扩频的研究与仿真代码(MATLAB-based direct sequence spread spectrum code and Simulation Study)

speechtimefre 语音时域处理(speechtimefre voice at the Domain)

color detection used to find color in images

说明：  一个非常不错的统计学习工具包，里面有详细帮助说明 用起来比较方便(A very nice package of statistical learning tools, there are detailed instructions to help them more convenient to use)

说明：  Jacobi的matlab程序是我同学编着玩的，我试了一下挺好，Jacobi迭代算法。(Jacobi s matlab program is edited by students, I play, I tried some very good, Jacobi iterative algorithm.)

该代码是自己利用实际的大气污染数据编写的否定选择算法例程，验证否定选择算法的分类效果(The code is their actual air pollution data using negative selection algorithm written routines to verify the effect of negative selection algorithm classification)

tow combination or binomial coefficient, factorial and sort function

说明：  BCH码的仿真，系统自带库函数BCHencode和BCH的code，支持任何非本原BCH和本原BCH码仿真，包含交织模块，支持matlab2017b以上(BCH code simulation, the system comes with library functions BCHencode and BCH code, supports any non-primary BCH and primitive BCH code simulation, including interleaving module, supports matlab2017b and above)

说明：  利用matlab仿真实现载波的平方环载波同步,costas环载波同步和符号同步(The square loop carrier synchronization, Costas loop carrier synchronization and symbol synchronization are realized by MATLAB simulation)

this code can be use in interpolation of seismic data.
