Solution of Laplace equation in an semi-circle region by FEM method

和Huffman-Tree一样，Shannon-Fano coding也是用一棵二叉树对字符进行编码。但在实际操作中呢，Shannon-Fano却没有大用处，这是由于它与Huffman coding相比，编码效率较低的结果（或者说香农-范诺算法的编码平均码字较大）。(And Huffman-Tree, like, Shannon-Fano coding is using a binary character coding. However, in practice it, Shannon-Fano, but not much use, since it is compared with the Huffman coding, coding efficiency is the result of a lower (or Shannon- Fano coding algorithm larger average code word).)

利用FDTD方法计算简单目标（如：方柱）的RCS，通过迭代求解，近远场外推，得到远区场的结果 (Using the FDTD method to calculate the RCS of simple objects(such as square column), through iterative solution, Near far field extrapolation to get the results of far field)

用MATlabgui编写的登录密码的例程，该例程可新注册密码。并对上一版改版。(Written by MATlab gui login password routine, the routine can register a new password. And on a revised version.)

说明：  主要用于数学建模的算法，比如路径规划中的最短路径，数据的拟合分析以及随机数的产生等。(It is mainly used in mathematical modeling algorithms, such as the shortest path in path planning, data fitting analysis and random number generation.)
