盒维数计算和豪斯多夫维数的计算与应用研究程序(box counting)

说明：  算法知识讲解，是一本不错的算法入门级教材的pdf版本(This is a good introduction to algorithm)

excel宏的SPI计算，降水指数。非常详细的说明(The excel macro SPI precipitation index. Very detailed description of)

说明：  可实现Dijkstra算法，显示起始点到其它各节点的最短距离和路径(Dijkstra algorithm can be implemented to show the shortest distance and path from the starting point to other nodes.)

有限元计算控制加载中弧长法（arc-length）的matlab源程序(Loading FEM arc length control method (arc-length) matlab source)

MFC编写的计算器，基本功能都已实现，加速键没有实现(Written in MFC calculator, basic functions have been achieved, not achieved accelerator)

新建复数类进行复数运算，重载+、=+、*、/等运算符用于复数间的运算。(New complex class complex operation, overloading+ =+,*,/operator for computing the plural.)

不可压缩后稳态径向滑动轴承润滑计算方法，等刚度，不考虑负压(Incompressible steady-state radial sliding bearing lubrication calculation method on the stiffness, do not consider the negative pressure)

上三角或下三角矩阵也有大部份的元素不储存值（为0），我们可以将它们使用一维阵列来储存以节省储存空间，而对称矩阵因为对称于对角线，所以可以视为上三角或下三角矩阵来储存。(Upper or lower triangular matrix or a large majority of elements are not stored value (0), we can use them to store a one-dimensional array in order to save storage space, and because the symmetrical diagonal symmetric matrix, it can be regarded as the or lower triangular matrix storage.)

说明：  该程序用有限元方法来处理标量亥姆赫兹方程，其实例是脊形介质波导中的光波。(The functino of the code is to slove Helmholtz equation by using finite element method (FEM). The example is an optical waveguide.)
