应用于PET的蒙特卡罗仿真方面的资料，可以用来作为指导性文献(monte carlo simulation that is applied in the pet image reconstruction.)

利用粒子群优化算法实现两个变量求最大值，很实用的一个matlab程序(Particle Swarm Optimization)

离散随机系统的Bayes辨识法，matlab程序(Bayes discrete stochastic systems identification method, matlab program)

Matlab indentification

应用REF实现地下水位预测，可以在MATLAB中完美运行，好的思想，值得交流。(Application of REF to realize the prediction of groundwater level, can run perfectly in MATLAB, good ideas, worthy of exchanges.)

说明：  蒙特卡洛简单示例，适合初学者，简单容易，吐血整理(Monte Carlo simple example, suitable for beginners, simple and easy, vomiting blood)

此MATLAB程序用于自相关函数的估计（包括直接法和FFT法），信号的频率估计（包括MUSIC, ROOTMUSIC，ESPRIT和MVDR）和功率谱的估计（包括LevinsonDurbin迭代法，BT法和周期图法），并附带相应的仿真图以便于对比(MATLAB for correlation estimate :direct and FFT transform frequency estimate of signals:MUSIC, ROOTMUSIC，ESPRIT和MVDR power spectrum estimate : LevinsonDurbin and BT,corresponding figures are accompanied to compare)

信噪比，计算公式是信号能量比上噪声能量，有助于分析信号成分的(Signal-to-noise ratio, and the calculation is signal energy on energy than noise, help analysis of signal components )

estimates a GARCH(1,1) under the assumption that residuals are normal

研一上学期，学校开了数值分析这门课，而且要求用matlab进行上机试验，经过一段时间的学习，对matlab有了最初步的了解，结合所学课程，废了好大的劲才编了几个小程序，希望对后来学习的人有点帮助。(Kenichi last semester, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, after a period of learning, of matlab with the most basic understanding, combined with the course, the repeal of several large series劲才a few small programs, and they hope to learn a little bit later to help.)
