E meter application for single phase

this matlab function finds peaks of a plot. it takes a coordinate matrix as an input. also removes redundent peaks (for instance, in case of a step plot, it finds one peak)

利用两层BP神经网络训练加权系数。隐含层的激活函数取S型传输函数，输出层的激活函数取线性传输函数(Weighting factor of two layers of BP neural network training. The hidden layer activation function to take the S-shaped transfer function, the output layer activation function to take a linear transfer function)

Cipher Block Mode for Authentication.

本代码是ja-sw 矢量磁滞模型的混合模型的代码，有两部分一部分是ja模型，另一部分是sw模型，两者混合变为矢量磁滞模型(This code is ja-sw vector hysteresis model hybrid model of the code, there are two parts ja model part, the other part is sw model, a combination of both into a vector hysteresis model)

以GUI实现指纹的识别和匹配百分比,中间有对指纹的二值化，M连接，特征提取等处理(GUI fingerprint recognition and matching percentage, the middle of the fingerprint binarization M connection, feature extraction and processing)

最小均方误差（MMSE）的算法，包含位置式PID算法、积分分离式PID，是小学期课程设计的题目，仿真效率很高的，用于信号特征提取、信号消噪，大学数值分析算法，处理信号的时频分析，合成孔径雷达（SAR)目标成像仿真。( Minimum mean square error (MMSE) algorithm, It contains positional PID algorithm, integral separate PID, Is the topic of the elementary school stage curriculum design, High simulation efficiency, For feature extraction, signal de-noising, University of numerical analysis algorithms, When processing a signal frequency analysis, Synthetic Aperture Radar (SAR) imaging simulation target.)

这是进行IGA分析的 Matlab代码.可用于进行1维，2维和三维的线弹性问题分析，并可以进行裂纹的扩展，夹杂等的计算。同时，包括Eular梁和Kirchhoff板在内的结构力学问题也可行。 (This is the the Isogeometric Analysis (IGA) Matlab code. The code supports one, two and three dimensional linear elasticity problems. Extended IGA for hole, inclusion and crack modelling is also implemented. Structural mechanics problems including Euler beam and Kirchhoff plates (rotation-free formulations) are implemented as well.)

很难得WEB。内部资料。初学者必看的，也是工程师们的良好的基础资料(A rare WEB. Internal data. Beginners a must-see, but also engineers a good basic information)

it is used seperate framses from an video and to extract as jpeg images
