Gradient-Descent

说明：  matlab实现霍夫曼编码，计算编码效率并分析结果(matlab huffman code)

说明：  fastica实测数据，可以做数据的预处理，保留有用信号，滤除噪声(FastICA measured data, can do data preprocessing, retain useful signal, filter noise)

核Fisher鉴别分析方法（KFDA）。KFDA方法的基本思想是首先将原始训练样本通过一个非线性映射 映射到某一高维(可能是无限维)特征空间F中，然后在F中执行Fisher鉴别分析。(Nuclear Fisher discriminant analysis method (KFDA). The basic idea of KFDA method is the first original training data by a nonlinear mapping  mapped to a high dimensional (possibly infinite dimensional) feature space F, then F in the implementation of the Fisher discriminant analysis.)

这里是通信领域中各种基带信号（非常全，几乎最新的都有），用matlab编写，给出了相应的带宽和功率谱密度，很值得学习通信的看看(Here are the various communications baseband signal (very full, almost all the latest), written with matlab, the corresponding bandwidth and power spectral density, it is worth learning to see communication)

是关于混合粒子群的一个程序，解决旅行商问题的。简单易懂。(PSO TSP)

说明：  实现两电平she控制，并通过算法得到其调制角(The two-level she control is realized and the modulation angle is obtained by algorithm)

仿真了锁相环工作到一定时间后达到锁定状态的过程，程序采用的是一阶RC低通滤波器即二阶一型环(Simulation of the PLL to work until after a certain period of time to achieve lock-state process, the procedure is used first-order RC low-pass filter that is second-order one-ring)
