基于haar-like训练的人脸识别，在matlab中实现的，希望对大家有用。(Training based on haar-like face recognition, implemented in matlab, we want to be useful.)

计算电力系统概率问题，使用matlab编写描述电力系统稳定性(Calculate the probability of power system problems, the use of written descriptions of power system stability matlab)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

说明：  大家好，本程序功能是VC环境下Matlab组件后绑定的实现，希望对大家有所帮助(Hello everyone, this program features is the VC environment Matlab after the binding components to achieve, I hope all of you to help)

径向基函数神经网络的优点：逼近能力，分类能力和学习速度等方面都优于BP神经网络，结构简单、训练简洁、学习收敛速度快、能够逼近任意非线性函数，克服局部极小值问题。原因在于其参数初始化具有一定的方法，并非随机初始化。代码为RBF的matlab程序，可以使用但是需要自己配置数据。(Radial Basis Function Neural Network (RBF-NN) has the advantages of better approximation ability, classification ability and learning speed than BP Neural Network (BP Neural Network). It has simple structure, simple training, fast learning convergence, and can approximate any non-linear function to overcome the local minimum problem. The reason is that its parameter initialization has a certain method, not random initialization.)

这个是我对于模糊pid控制自己进行的simulink仿真，很有用。(This is my fuzzy pid control themselves for the simulink simulation, very useful.)
