分水岭测试算法，供参考，里面还有一些其他代码，共学习(Watershed test algorithm, for reference)

Identifying overlapping period in time series. Required input: X = structure with in every cell (X{cell}) a measurement station. every cell has its first three columns as [year,month,day] Output: begin_date = is beginning date of overlapping periods end_date = end date of overlapping periods output = structure with overlapping periods filtered numcell = number of measurement stations

A* uses a best-first search and finds a least-cost path from a given initial node to one goal node

说明：  条件语句是编程中最常用的结构，这里作一个演示结果的文件(conditional statement is the most commonly used programming structure here for a demonstration of the results of the document)

采用分层的前推回代法应用于n节点的电力系统，收敛速度快，准确度高，电力系统配电网潮流计算。(Layered forward and backward substitution method used in the power system of n nodes, the convergence speed, accuracy, power system with the power flow calculation.)

仿真BPSK调制在AWGN信道下分别使用卷积码和不使用卷积码的性能。(Simulation BPSK modulation in the AWGN channel with a convolutional code, respectively, and not using the performance of the convolutional code.)
