Optimization6

本源码目的在于查找一幅图像中个图形的重心，基于matlab，找出重心后标记出来，并显示。(The Source aims to find an image in a graphics core, based on matlab, after the marked identify the focus, and display.)

按照给定指标采用模拟低通滤波器（巴特沃思低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(Indicators in accordance with a given analog low-pass filter (Butterworth low-pass) to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, the digital filter.)

一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(A four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)

蒙特卡洛模拟方法与应用，介绍的比较全面很详细(Monte Carlo simulation methods and applications, described in detail a more comprehensive)

实现目标物体的检测，包括人脸检测，快速移动物体的检测，以及PCA算法等(Realize the object detection by Matlab,include face detection and fast motion detection and so on.)

能够进行电弧特性的仿真，对接地故障有一定的参考价值和意义(It can simulate the arc characteristics and has certain reference value and significance for ground faults.)

说明：  Matlab源代码，是一些教科书上用到过的代码。(Matlab source code is that some textbooks had used the code.)

说明：  AR.m的matlab源程序，用于预测模型使用，别人给的！(AR.m matlab source code for the prediction model using someone else' s!)

matlab入门教材，讲解的内容比较基础，适合初学者学习(matlab introductory textbook to explain the contents of the basis for comparison, suitable for beginners to learn)
