求一个信号的频谱分布，并求某一帧的频谱图。(Seeking a signal of the spectrum distribution, and the frequency spectrum diagram of the requirements of a certain frame.)

这个程序主要是用来设计实现一个加解密的系统 采用matlab设计 用了二进制循环 异或的知识(This program is mainly used to design and implement a system of encryption and decryption using matlab design cycle using the binary XOR of knowledge)

应用于PET的蒙特卡罗仿真方面的资料，可以用来作为指导性文献(monte carlo simulation that is applied in the pet image reconstruction.)

说明：  Wind Turbine Driven Doubly-Fed Induction Generator with Grid Disconnection

一本很好的matlab学习书籍，综合了很多的内容，英文版的，对英文又要求( Matlab learning good book, synthesized a lot of content, the English )

也是最优路径问题，编译后会得到一个最短的路径(Is the optimal path problem, the compiler will get a shortest path)

Used to make fast Source Code for Andriod.

说明：  毕业设计非常有用的脑电信号，本人亲测，效果不错，贡献给大家。(Graduate design very useful EEG, I pro-test, the effect is good, to the party.)

二维FDTD程序，采用Mur吸收边界，实现了较好的吸收效果，可以用来与UPML吸收边界比较。(2D FDTD program, the Mur absorbing boundary to achieve a better absorption, can be used with UPML absorbing boundary.)

对于Ldpc码，测试其校验矩阵H有无4环的存在，避免因为存在4环影响性能(For Ldpc code, test whether the check matrix H of the existence of loop 4, loop 4 to avoid because of the impact of performance)
