学习matlab的GGSJ小程序，没问题额(Matlab program to learn the GGSJ small, the amount is no problem)

this is a book to learn English TOEIC

总结了matlab与vc混合编程的三种常用方法，并结合了具体的实例，简单介绍了基本的操作(Matlab and vc summarized three common hybrid programming method, and specific examples, a brief introduction of the basic operations)

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.)

在傅立叶变换光学中夫琅和费衍射场的强度分布就等于屏函数的功率谱。因此我们可以直接将光屏进行傅立叶变换，再处理得到衍射图样。(In the Fourier transform optics, Fraunhofer diffraction field intensity distribution is equivalent to the power spectrum display function. Therefore, we can directly Guangping Fourier transform, and then to handle any diffraction pattern.)

设雷达信号是码宽为0.5微妙，中心频率是10MHz的7为巴克码2PSK信号，接收的雷达回波中频采样频率为为40MHz，中频进行正交下变频。假设在13.5km处有一个点目标，仿真该雷达的脉冲压缩处理。 已通过测试。 (Let the radar signal is yards wide 0.5-subtle, the center frequency of the the Buck the code 2PSK signal, the received radar echo IF sampling frequency of 10MHz to 40MHz, IF quadrature down-conversion. Assuming the 13.5km at a point target simulation of the radar pulse compression processing. Has been tested.)
