异步电机矢量控制仿真模型，比较基本，已通过测试，完全好用。(Vector control induction motor simulation models, more basic, has been tested to be fully useful.)

说明：  生物特征识别技术作为一种身份鉴别手段具有独特的优势。在生物特征识别系统中, 采集数据的预处 理是不可或缺的环节。以人脸识别为例, 介绍了一种在复杂背景的彩色图像中, 基于颜色和知识的生物特征预处理 方法。首先利用颜色信息从图像中分割出类肤色区域, 然后运用人脸几何特征和眼睛的提取定位人脸。仿真实验表 明, 该算法能较为准确地定位彩色图像中的正面或小角度偏转的人脸, 具有较快的运算速度。(Biometrics as an identification tool has a unique advantage. In biometric systems, collect data preprocessing is an indispensable link. To face recognition, for example, presents a complex background in color images based on color and knowledge of the biological characteristics of pretreatment. The first to use color information to separate out the classes from the image color region, and then use face extraction of geometrical features and eye positioning face. Simulation results show that the algorithm can be more accurately locate color images in a positive or small-angle deflection of the face, with a faster computational speed.)

给定某项Zernike系数能够绘出对应的三维、二维图像，支持合并功能的GUI计算器。(Given a Zernike coefficient can draw the corresponding three-dimensional, two-dimensional images, and support combined function GUI calculator.)

利用ＶＣ＋＋与ＭＡＴＬＡＢ编程 希望多交流 也希望资源共享(VC++ and MATLAB programming hope that more exchanges also hope that the sharing of resources)

本代码为智能天线中，基于圆阵的MUSIC算法(Multiple Signal Classification（music）)

说明：  ：本文通过对伽尔顿板实验的过程及结果与混沌运动的特征进行比较分析，说明伽尔顿板实验不仅 是使人们认识多粒子无规则运动中粒子遵循统计规律的典型，还可以作为说明混沌运动特征的很 好示例。(: Based on the Jiaer Dun board process and results of experiments with the chaotic motion of a comparative analysis of the characteristics that Mingjiaerdun plate test is not only to create awareness of multi-particle random motion of particles follows the typical statistical law, but also as an illustration Characteristics of a good example of chaotic motion.)
