FFT

matlab编的人工鱼群算法程序，已经编译通过，非常优秀的算法，希望大家改进应用到实践中去(matlab code of the artificial fish school algorithm procedure has been compiled by a very good algorithm, I hope we improve the application in practice)

matlab实现的插值,对初学都很有帮助(matlab implementation of the interpolation, are very helpful for beginners)

基于pso_lssvm的预测程序，直接可用，可以出图，可以修改。加入了粒子变异、权值的递减策略（去掉%就行了）。注意：excel记得放对位置(Pso_lssvm based prediction program, directly available, you can map, you can modify. Added a particle mutation, weight reduction strategy (remove%))

说明：  matlab的基本例题的知识内容，一些常见的编程都包含，请参考(matlab basic example of the intellectual content of some common programming are included, please refer to)

1.产生正弦信号，方波信号，均匀噪声； 2.信号的叠加； 3.信号的相关分析； 4.信号的卷积； 5.信号的和； 6.信号的频谱图。(1. Generate sine signal, square wave signals, uniform noise 2. Signal superposition 3. The signal correlation analysis 4. The convolution of signal 5. The sum of signal 6. The signal spectrum.)

认知无线电频谱感知匹配滤波器检测仿真，选用FM信号，分析了虚警概率(Matched filter spectrum sensing cognitive radio simulation testing, the choice of FM signals, analysis of the probability of false alarm)
