　　这包括代码为“扩展”和“减少”程序,对高斯图像金字塔,探讨了作为一个紧凑的拉普拉斯金字塔图像编码”-伯特和Adelson,1983年。 　　 　　重要的应用同样的包括运动估计精度等。(This contains the code for the Expand and Reduce routines for Gaussian image pyramids, as discussed in the Paper- " The Laplacian Pyramid as a Compact Image Code"- Burt and Adelson, 1983. Important applications of the same include motion estimation etc.)

Induction motor model with scalar control

This code is for DWT Chain process in filtering

一天文学家要确定一棵小行星的运动轨道，他在其轨道内建立了以太阳为原点的直角坐标系，由开普勒第一定律知小行星的运动轨道为一椭圆，试确定行星的运动轨道。(One day in literature to determine the orbit of an asteroid, he set up in its orbit to the sun for the origin of the coordinate system, by Kepler s first law of motion track known asteroid is an ellipse, the orbits of planets.)

解释结构模型(ISM)的matlab学习程序，通过输入邻接矩阵及其维数，计算出因素的分级，以及可达集、先行集和共同集。(Interpretative Structural Model (ISM) in matlab learning program, by entering the adjacency matrix and its dimension, calculate grading factors, as well as arrive set, first set and a common set.)

这是我搭建的10W小功率太阳能电池模型，可根据实际情修改太阳能光伏电池的功率、短路电流、开路电压、额定电流和额定电压。另外还有最大功率跟踪模型和高频升压逆变模型也传上来，做得比较简单，有需要的可以参考一下~(Solar photovoltaic power generation system)

本演示文稿介绍了MATLAB的一些基本知识，希望对学习MATLAB的朋友有一定的帮助(This presentation describes some basic knowledge of MATLAB, in the hope to learn MATLAB is certainly helpful friends)

切比且夫线阵幅度加权方向图计算,画出二位方向图,图示中标示出增益,副瓣电平等(Ratio and the linear amplitude weighted directional graph computation, draw two direction map, marked gain the diagram, the sidelobe level etc. )

ALOHA协议的思想很简单，只要用户有数据要发送，就尽管让他们发送。当然，这样会产生冲突从而造成帧的破坏。但是，由于广播信道具有反馈性，因此发送方可以在发送数据的过程中进行冲突检测，将接收到的数据与缓冲区的数据进行比较，就可以知道数据帧是否遭到破坏。(ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.)
