一篇很好的关于肌电信号的综述性文章，希望对大家有用(A good overview of the EMG signal on the article, I hope to be useful)

对carmaker软件进行了介绍，对汽车仿真有很大的帮助，促进汽车的生产。(Software for the carmaker introduced, car simulation of great help to promote the production of cars.)

Shape variation of the Gaussian pulse

CankNicolson scheme to solve the diffusion equation for different initial conditions

同时有图像matlab的说明，运动捕捉系统的重新构建，更良好的解决了出现噪点的情况(very good)

以matlab为工具利用数字图像处理技术对答题卡进行了识别，并对识别结果进行了处理。注意到答题卡在采集图像的过程中由于各种原因可能会产生图像倾斜、水平或垂直错位，要进行正确识别首先必须对其进行校正，再依据像素检索技术进行识别。(With MATLAB as the tool, the answer card is identified by digital image processing technology, and the recognition results are processed. It is noted that the answer card in the process of collecting images may cause image tilt, horizontal or vertical dislocation for various reasons. To correct recognition, it is necessary to correct it first and then identify it according to the pixel retrieval technique.)
