某市有一码头，每次仅容一辆船停泊装卸货，由于经常有船等候进港，部分人提出要扩建码头。经过调查历史资料发现，码头平均每月停船24艘，每艘船的停泊时间为24±20小时，相邻两艘船的到达时间间隔为30±15小时，如果一艘船因有船在港而等候1小时，其消耗成本为1000元。经预算，扩建码头大约需要1350万元，故市长决策如下：如果未来五年内停泊船只因等候的成本消耗总和超过扩建码头花费则扩建码头，否则，不予扩建。因此，希望你能够帮助市长做出决策。此问题已知到达的大概时间和大概停泊时间，对于此问题用概率统计的方法来做比较复杂，可用程序随机产生到达时间和停泊时间来模拟未来五年内船的停泊，多次模拟预测停泊情况，以做出决策(。-Problem in a city with a terminal expansion dock, each only allow a boat moored loading and unloading, as often there are waiting boat into port, some people proposed to expand pier. Terminal stopping 24 per month, per vessel berthing time of 24 ± 20 hours, the arrival of two adjacent vessels interval 30 ± 15 hours, if a ship due to boat in the harbor while waiting for one hour, and its consumption cost of 1,000 yuan. The budget of about 13.5 million yuan expansion dock, so the mayor decision as follows: If a ship is moored next five years, the cost of waiting more than the sum of consumption spending is expanding marina pier extension, otherwise, not expanded.)

能够实现四步相移解包裹，对包裹相位能较好的分离出来(unwrap algorithm)

电力系统经济调度程序，很使用，适合初学者(Power system scheduler, economic, use is suitable for beginners)

多相合成：将多个窄带信号合称为一路宽带信号，合成后的信号频率无相互干扰(The multi-phase synthesis: multiple narrowband signals collectively known as the way broadband signals, the synthesized signal frequency interfere with each other)

说明：  雅克比迭代法求解方程组;雅克比迭代法就是众多迭代法中比较早且较简单的一种，其命名也是为纪念普鲁士著名数学家雅可比。雅克比迭代法的计算公式简单，每迭代一次只需计算一次矩阵和向量的乘法，且计算过程中原始矩阵A始终不变，比较容易并行计算。(Jacobian iterative method for solving equations Jacobi iteration is one of the earlier and simpler iteration methods, and its name is also in memory of Jacobi, a famous mathematician in Prussia. Jacobian iterative method has a simple calculation formula, each iteration only needs to calculate matrix and vector multiplication once, and the original matrix A is always the same in the calculation process, so it is easy to parallel calculation.)
