对于水轮机阀门开启、关闭的一瞬间，对于钢管有比较大的水击。该程序计算出了相对最大的水击压力。(For turbine valves opened, the closure of the moment, for a relatively large pipe water hammer. The program calculated the maximum relative pressure of water hammer.)

说明：  用四阶Runge-Kutta法解延迟微分方程组，用到的朋友看一下啊(Using fourth-order Runge-Kutta method for delay differential equations, a friend used to look at ah)

高频地波雷达回波信号二维傅里叶变换仿真处理，通过该变换可以得到海上目标的速度和距离信息。(HF ground wave radar echo simulation of two-dimensional Fourier transform processing, the adoption of the sea can transform the speed and distance from goal information.)

说明：  恒模算法的简介，它适用于信道的盲均衡。Matlab程序提供基本的框架，可以修该里面的参数以测试该算法的性能(CMA briefings, which applies to Channel Blind balanced. Matlab to provide a basic framework, it can be done inside of the parameters to test the performance of the algorithm)

说明：  c++语言求解稀疏矩阵方程组的ICCG法源程序。参考：《工程电磁场数值计算分析与综合》 附录（Fortran90）.(c++ solves sparse matrix equations with the ICCG method.Reference: &quot Analysis and Synthesis of Numerical Electromagnetic Field ,&quot Appendix (Fortran90).)

说明：  对该模型参数辨识采用递推最小二乘法，即 RLS（ recurisive least square）， 它是一种能够对模型参数进行在线实时估计的辨识方法。(The recursive least square method is used to identify the parameters of the model, that is, rls (recurisive least square), which is an online real-time estimation method for the model parameters)

说明：  飞机气动计算流体力学分析的经典之作,值得学习的好书(a excellent book about aerodyanmics introduction)

本算法是求取点到曲线的距离，希望对大家有帮助(the algorithm is to strike a point of the distance curve, and I hope to be helpful)

说明：  GM（1，1）灰色模型，便于了解其混沌特性，程序很短，由matlab编译，(GM (1,1) gray model to facilitate understanding of their chaotic behavior, a very short procedure, Matlab Compiler,)
