利用罚函数法求解下列问题：求f=x1^2+4*x2^2的最小值，其中要满足：x1-x2-1≤0 -x1-x2+1≤0 x2-1≤0 (Using penalty function method to solve the following questions: o f = x1 ^ 2+ 4* x2 ^ 2 minimum value, which will meet: x1 x2-1-0 or -x1 x2+ 1 or 0- X2-1 or 0 )

自己写的一个锁相环程序，希望对大家有所帮助(A phase-locked loop to write their own procedures, we hope to be helpful)

这个例子示出了充放电时的超级电容器的模式。该电路示出了与电池超级电容器的一个简单的杂交。超级电容器被连接到降压/升压转换器和电池连接到升压转换器。电池的功率由一个速率限制器块，因此瞬态功率由超级电容器供给到DC总线限制。(This example shows the supercapacitor model during charge and discharge. The circuit illustrates a simple hybridization of a supercapacitor with a battery. The supercapacitor is connected to a Buck/Boost converter and the battery is connected to a Boost converter. Power of the battery is limited by a rate limiter block, therefore the transient power is supplied to the DC bus by the supercapacitor.)

在现代谱估计中，用自相关的无偏估计代替周期图中自相关函数的有偏估计，可能导致出现负的谱估计值，因此采用BT谱估计器的方法(In the modern spectral estimation, the use of self-related unbiased estimate the figure to replace the cycle of auto-correlation function biased estimate may lead to a negative estimated value of the spectrum, so the use of BT s method of spectral estimation)

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.)

一维情况下用ＦＤＴＤ方法模拟电磁波的传播情况，加了吸收边界条件，用Ｃ和MATLAB混合编程，信号源是高斯脉冲(One-Dimensional FDTD simulation with the propagation of electromagnetic waves, plus the absorbing boundary condition, mixed with the C and MATLAB programming, the signal source is a Gaussian pulse)
