应用于水利上河流的流管划分，输入断面数据和划分流管数量进行流管划分。(Applied to the flow tube is divided on river water conservancy input section data and divided the number of stream flow tube pipe division.)

DPWMMIN调制，在matlab2014A验证，可以运行。(DPWMMIN modulation, has been verificated in the matlab2014A.)

内点法最优潮流程序,可供参考一下，内容可以较大修改(the program of inner-point optimal power flow)

采用的是规则网格进行的波场模拟，该方法是对一阶的声波方程进行的模拟，应用了二阶的精度 (Uses a regular grid for the wave field simulation, the method is an order of the acoustic wave equation simulation, the application of the second-order accuracy)

文件给出了几个典型的雷达杂波的小程序：瑞利杂波，相关对数正态分布杂波，相关weibull分布杂波和相干相关K分布杂波。(Document gives a few typical small radar clutter process: Rayleigh clutter, clutter-related log-normal distribution, weibull distribution related clutter and coherent K distributed clutter related.)

说明：  现代电力系统分析的书籍，其中包括直流线路、交直流混联电网、潮流计算等多项内容(Books of modern power system analysis, including the DC Circuit, AC and DC hybrid power flow calculation and many other content)

说明：  This code is for fingerprint recognition

this is a basic face detection system.

运用P-R状态方程，迭代计算甲烷气体压缩因子(The use of PR equation of state, iterative calculation of methane gas compressibility factor)

PQ分解法，有些还需要改进，该程序所对应的例子是东南大学陈珩编的《电力系统稳态分析（第二版）》的例4-5(PQ decomposition, some also needs to be improved, The procedure corresponding to the example of Southeast University, Chen Heng addendum to the "steady-state power system analysis (second edition)" 4-5 cases)
