说明：  实现人脸检测的功能，对合适大小的图像，将其放在相应的matlab文件夹下即可自动进行人脸检测并定位。(For face detection function, the size of the image on the right, put it in the appropriate folder automatically matlab for face detection and localization.)

用牛顿拉夫逊法的极坐标形式计算电力系统潮流(Newton Raphson method polar form power flow calculation)

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：  BP神经网络异或问题 使用说明：打开文件夹中的BP.m文件，在matlab中运行此m文件，即可在command window中得出结果。压缩包内附说明文件 (XOR problem of the BP neural network for use: Open the folder in BP.m file, run this m file in matlab to the outcome of the command window. Compression package containing the documentation)

多变量PID调谐功率单元机组的非线性控制(Multivariable PID tuning Power Generating Unit and nonlinear control)

ofdm 程序，包括了信道估计以及相应的算法设计，是理解ofdm好的版本。(fodm It has included the channel estimate as well as the corresponding algorithm design, understands the ofdm good edition )

二维相位解包裹算法。主要基于结构光采集以及其他需要对于包裹相位进行解相的算法。包括最小枝切法以及相位图法。(2D unwrap algorithm mainly based on the structure light)
