some useful definitions in project designs

PSO寻优算法，能够帮助初学者学习PSO算法，并且进行实际应用(PSO optimization algorithm, PSO algorithm can help beginners learn, and practical application)

刚刚完成的一个用Matlab实现画中画的功能，代码简洁，很实用！代码+仿真结果！(Just completed implementation of a PIP function with Matlab, the code is simple and it works!)

matlab的模式识别toolbox，将它解压缩，拷贝到matlab目录下的toolbox下，声明：请不要将这个工具箱应用到商业用途上，仅作学术参考。(pattern recognition tool box. Please unzip, copy it under the directory of matlab toolbox. Announcement: Don t apply it to commercial usage, just for research reference.)

粗糙惩罚算法，此算法能够分辨光谱数据中的坏点，并对坏点加以惩罚，即减小该点的权重值，从而使得数据更加真实平滑。(Roughness Penalty Smoothing)

几种特殊函数(伽马，超几何，贝塞尔）的计算代码(Several special functions (gamma, hypergeometric, Bessel) calculation code)

MATLAB的入门书籍，编写思路清晰，内容偏基础，适合刚入门的同学学习。书的页码不多，在很少的时间内就可以完成。(MATLAB study books for begineers, which writing with clear ideas, content-based bias for students just getting started learning. Book have little pages and easy to complete.)

粒子群优化算法，粒子群优化算法基本流程，稍加修改即可应用(Particle Swarm Optimization)

Finite impulse response filter

matlab程序，对一个混沌系统进行仿真。 lyapunov.m是计算的主程序；qi_hyper.m是一个例子（qi系统），利用qi_hyper_lyap.m计算所有李氏指数，利用qi_hyper_lyapDim.m计算分形维数。其他系统稍作改正就可使用。经验证程序比其他计算李氏指数的更为有效精确。(matlab program for a simulation of chaotic systems. lyapunov.m are calculated in the main program qi_hyper.m are a case in point (qi system), the use of all qi_hyper_lyap.m calculated Lyapunov exponent, using qi_hyper_lyapDim.m calculated the fractal dimension. Other systems can be used to make some corrections. Experience in the certification process than any other computing Lyapunov exponent of the more effective precision.)
