阵列信号处理中的后向平滑！ 属于原创啊。。。。。。。。。。。。。。。(array signal processing: Backward Spatial Smoothing)

找函数的零点位置， 返回的是零点的index。 被找的函数须是连续函数 (Find zero points index of a continous function)

根据所点击选择的三个点，进行自动画圆的程序。(Click to select the three points, the program automatically draw a circle.)

典型模拟通信系统仿真 增量调制 PST编码 FSK 汉明码(communication system modulation)

利用Peng_Robinson EOS 计算常见纯组分气体逸度和密度。利用matlab运行求解。(Peng Robinson is used to calculate the density and fugacity of single component gas at given pressure with Peng-Robinson equation.)

说明：  NPC三电平仿真, matlab仿真，2017版本(NPC 3level invrter simulation)

函数功能：本函数将完成对输入图像的峰值信噪比计算(Function: This function will be completed on the input image of the peak signal to noise ratio calculation)

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.)
