说明：  递归，是函数实现的一个很重要的环节，很多程序中都或多或少的使用了递归函数。递归的意思就是函数自己调用自己本身，或者在自己函数调用的下级函数中调用自己。 递归之所以能实现，是因为函数的每个执行过程都在栈中有自己的形参和局部变量的拷贝，这些拷贝和函数的其他执行过程毫不相干。这种机制是当代大多数程序设计语言实现子程序结构的基础，是使得递归成为可能。(Recursion, is a function to achieve a very important part of many programs are more or less use the recursive function. Recursive mean that the function of its own call to themselves or subordinates in their own function calls a function to call their own. Recursion that can be achieved because the function of each execution in the stack has its own shape parameters and local variables of the copy, the copy and the implementation process has nothing to do other functions. This mechanism is the most modern programming language implementation subroutine structure of the foundation is to make recursion possible.)

说明：  matlab中distance函数的详细描述及其使用方法，以及将换算到直角坐标下的公式(in matlab，distance function details，using)

本程序用于线性调频信号频率的测量，首先产生一加噪线性调频信号，再使用小波滤波去除噪声，最后使用希尔伯特变换法求信号的频率。(This procedure is used to measure the frequency of chirp signal, first generate a chirp signal with noise, and then use wavelet filtering to remove noise, and finally use the Hilbert transform method for the signal frequency.)

一种无线通信系统中，重传技术并且有时间关联的outage的错误检查方法(A radio communication system, and a retransmission is associated with the outage time error checking method)

说明：  主成分分析算法，用于建立主成分分析模型，采用累计贡献率的方法(pca )

这是一个很好的matlab精对准的详细程序(This is a matlab fine alignment program)

本程序为模型预测控制程序的一种，自带实时计算更新模块，完成循环仿真。(This procedure is belong to the model predictive control algorithm, with real-time update module calculation to complete the cycle simulation.)
