Computer programming to calculate normalized frequency for different types of optical fibers.

一些常用数值分析程序，希望对大家有所帮助。(some commonly used numerical analysis procedures, we hope to help.)

本文提出了网络编码，减少了验证对飞块成本，有效地防止恶意块的传播实用的安全解决方案。在我们的方案中，用户不仅合作发布内容，但用户也合作来保护自己免受恶意用户通知受影响的节点时，一个恶意的块被发现。(This paper presents a practical security scheme for network coding that reduces the cost of verifying blocks on-the-fly while efficiently preventing the propagation of malicious blocks. In our scheme, users not only cooperate to distribute the content,but (well-behaved) users also cooperate to protect themselves against malicious users by informing affected nodes when a malicious block is found.)

这是在非正交（NOMA）环境下对用户的功率分配采用固定分配，前后用户功率比满足一定的要求(This is at a non-orthogonal (NOMA) environment on the user' s power allocation fixed allocation before and after the user power ratio meet certain requirements)

任意输入年，月，日，通过输入日期查看它是该年的第几天(Any input year, month, day, it is the first few days)

自然边界元方法理论知识，由余德浩教授编写，介绍了自然边界法在多种偏微分方层中应用。(Natural Boundary Element Method theoretical knowledge, written by Professor Yu Dehao introduces the natural boundary method in a variety of partial differential layer.)

一些干涉仪算法的代码，包括music算法，DOA估计，干涉仪测方位角(Code for some interferometer algorithm，such as MUSIC algorithm, DOA estimate)

说明：  长短期记忆神经网络，是一种时间循环神经网络，是为了解决一般的RNN（循环神经网络）存在的长期依赖问题而专门设计出来的，所有的RNN都具有一种重复神经网络模块的链式形式。在标准RNN中，这个重复的结构模块只有一个非常简单的结构，例如一个tanh层。(Long term and short term memory neural network)

说明：  本程序是用MATLAB编写，以后请MATLAB高手多进来切磋，请各位高手指教，看了后给点评价。谢谢！(this program is prepared using MATLAB, after many requests come in MATLAB master skills, the experts advise you please, after reading them to the point evaluation. Thank you!)
