"试验设计"是很多工程人员尤其是化学工作者经常要面对的话题，“试验设计”可以为我们的工作和科研节省大量的人力，物力和财力！本人结合自己在试验过程中的经历总结了所有设计过程中可能遇到的设计方案，并且把它们写成matlab源代码的形式，以此方便大家工作和学习上的使用。()

关于各类图象的攻击,如果滤波,噪音,锐化,JPEG压缩等等(Attacks on all types of images, if filtering, noise, sharpening, JPEG compression, etc.)

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：  采用人工智能神经网络的改进Holpfield神经网络解决旅行商问题(Improved use of artificial neural network neural network to solve the traveling salesman problem Holpfield)

以下几个matlab程序对雷达常用的线性调频信号（lfm信号）进行脉冲压缩时的关键问题进行了仿真，其中包括旁瓣抑制影响（加窗与不加窗）、多卜勒频移影响，并对时域脉压与频域脉压结果进行了对比分析，供相关技术人员参考。(The following several matlab programs simulate the key issues when pulse compression is performed on radar commonly used chirp signal (lfm signal), including sidelobe suppression effects (window and windowless), Doppler frequency shift effects, and The time-domain pulse pressure and frequency-domain pulse pressure results were compared and analyzed for reference by the relevant technical personnel.)
