随机牛顿法估计系统模型参数，揭示了许多算法的内在联系。(Stochastic Newton method to estimate the system model parameters, revealing the internal relations of a number of algorithms.)

分数阶傅里叶变换计算方面,仿真效率很高的，各种kalman滤波器的设计。( Fractional Fourier transform computing, High simulation efficiency, Various kalman filter design.)

海明加权的天线方向图，使用matlab 调试过，对研究雷达天线的同志很有帮助。(Hamming weighted antenna pattern, use the debug matlab, and the study of the radar antenna comrades helpful.)

金融时间序列data，著名的那本书的data (datafdfjkajfkd AIVAFDF)

层次分析法，是matlab编写的，仅作分享之用(AHP(analytic hierarchy process))

PDE processes for Heat flux

用MATLAB编写的时钟，希望对感兴趣的人有用(a clock code with matlab , hope useful to the one interested~)

该算法，解决了不收敛的问题，聚类效果非常好。改进的蚁群算法是基于遗传算法的改进，在基本遗传算法的基础之上，加入了变异因子，产生变异，从而更快的收敛。(The algorithm solves the problem of convergence, and the clustering effect is very good. The improved ant colony algorithm is based on the improvement of genetic algorithm. On the basis of the basic genetic algorithm, the variance factor is added to produce the variation, and the convergence is faster.)
