包含EM的介绍和对应的matlab程序.适用于初学者入门使用。(Includes the introduction and the corresponding EM matlab program. For beginner to use.)

matlab 自适应有限元方法，主要为二维椭圆型方程(Adaptive finite element method for two-dimensional elliptic equations)

里面包含了我搜集的一些关于matlab和sql的一些资料，主要用于matlab和sql的数据接口的连接，以及数据的存储。(Contains some information collected by me about some of the matlab and SQL, mainly used in matlab and SQL data interface connection, and data storage.)

说明：  四面体有限元程序,单元刚度的计算及总刚度矩征集成(tetrahedral finite element program modules stiffness of the total stiffness and assembly into Moment)

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.)

ofdma 的一些资料对于初学者是很有用的 学习也很方便(ofdma some information is very useful for beginners to learn is also very convenient)
