大家还记得小时候做数学题做到的幻方吗？如何用程序建立一个幻方呢？这就是一个简单的小程序，to make a magicsquare!(Remember when you do the math to do magic square it? How to create a magic square with the process? This is a simple little program, to make a magicsquare!)

说明：  雷达对导弹进行测距，导弹受气流扰动同时雷达观测存在观测误差，通过卡尔曼滤波对导弹距离进行估计(Radar is used to measure the range of missile. The missile is disturbed by airflow and there is observation error in radar observation. Kalman filter is used to estimate the range of missile.)

混沌控制的经典论文之一，希望对大家有帮助(chaos control，chaoscontrol，chaoscontrol，chaoscontrol)

说明：  用于功率预测的CNN代码，以及一系列相关函数文件(CNN Code for Power Prediction)

说明：  pca 源程序 能用，针对不同问题只要稍作修改即可。(pca)

自然边界元数学理论，于德浩教授编著。对于椭圆编制问题规划给出了较为详细数学理论解释，对于工程和理学专业的程序的编写有较好的辅助作用。(Natural Boundary Element mathematical theory, Professor Yu Dehao ed. For the preparation of the problem oval plan gives a more detailed explanation of the mathematical theory, for the preparation of professional engineering and Science program has a good supporting role.)
