说明：  这是一个小的应用程序，主要是MATLAB的应用(this is a little chengxu can help you )

一个慢跑者在平面上沿着他喜欢的路径跑步，突然一只狗攻击他，这只狗以不变的速度跑向跑步者，狗的方向始终指向跑步者，计算并画出狗的运动轨迹（如需其他条件，请自己假定）.(A jogger in the plane along the path he likes running, a dog suddenly attacked him, the dog ran at constant speed running, the dog always point to the direction of running, and calculate and draw the dog)

用Goertzel算法计算两正弦波信号的相位差(Goertzel algorithm using two-phase sine wave signals)

AN ANN BASED APPROACH FOR OPTIMAL PLACEMENT OF DSTATCOM FOR VOLTAGE SAG MITIGATION(Voltage sag has been considered as one of the most harmful power quality problem as it may significantly affect industrial production. This paper presents an Artificial Neural Network (ANN) based approach for optimal placement of Distribution Static Compensator (DSTATCOM) to mitigate voltage sag under faults. Voltage sag under different type of short circuits has been estimated using MATLAB/SIMULINK software. Optimal location of DSTATCOM has been obtained using a feed forward neural network trained by post-fault voltage magnitude of three phases at different buses. Case studies have been performed on IEEE 14-bus system and effectiveness of proposed approach of DSTATCOM placement has been established)

传输矩阵法计算光子晶体的的透射率的程序，运行环境是matlab软件，比较好用。(Transfer matrix method photonic crystal transmittance of the program, the operating environment is matlab software, relatively easy to use.)

数字识别，区分图片0到9，共有一百幅图片，一部分用来训练，一部分用来测试(Digit recognition, the distinction between image 0 to 9, a total of one hundred pictures, some for training, in part to test)

First a estimate of wireless sensor nodes is made and a network mesh will be created based on some topology techniques. A connection has to be established between Node I and all the vicinity nodes.
