Matlab code for FFT with two cos functions

给出了用雅克比方法解线性方程组的方法，文中给出了解三个线性方程的雅克比法(In this paper, a method of Jacques than the method of solving linear equations )

FILE SHOWS THE MODIFICATIONS FOR AODV.CC FOR INTRODUCING BLACKHOLE ATTACKS

lt码的MATLAB实现,程序绝对正确，并且非常完善(lt code MATLAB implemention，program is absolutely correct and very well.)

Ensemble修改程序，包括源程序和调用程序及实例。(Ensemble modify the program, including the source and call procedures and examples.)

核极限学习机，引入核函数解决ELM求解问题，一旦参数选定，结果就稳定下来，不再混入随机。在原来版本上加入自己理解改写，使得代码更容易理解。(Kernel extreme learning machine, kernel function is applied to deal with ELM to solve the problem, once the parameters selected, the result is stabilized, not randomly in the original version on becoming a member of their understanding, makes the code easier to understand)

采用AFC技术来锁定频，采用Garden技术进行定时恢复，采用Costas环进行相位的锁定(Use technology to lock the frequency of AFC, using Garden timing recovery techniques using Costas loop for phase locking)

MATLAB编程技巧，包含如何编写高速率和整洁的matlab程序，全英文的，值得参考。(MATLAB programming skills, including how to write high-speed and clean matlab program in English, it is worth.)

这是在matlab下实现的包络检波算法法。先对信号进行调制，然后进行包络检波。 (This is the method of envelope detection algorithm under Matlab. First signal modulation, and then proceed to the envelope detector.)
