The paper presents an efficient 88 line MATLAB code for topology optimization. It has been developed using the 99 line code presented by Sigmund (Struct Multidisc Optim 21(2):120-127, 2001) as a starting point. The original code has been extended by a density filter, and a considerable improvement in efficiency has been achieved, mainly by preallocating arrays and vectorizing loops. A speed improvement with a factor of 100 is obtained for a benchmark example with 7,500 elements. Moreover, the length of the code has been reduced to a mere 88 lines. These improvements have been accomplished without sacrificing the readability of the code. The 88 line code can therefore be considered as a valuable successor to the 99 line code, providing a practical instrument that may help to ease the learning curve for those entering the field of topology optimization. The paper also discusses simple extensions of the basic code to include recent PDE-based and black-and-white projection filtering methods

《功率变换器和电气传动的预测控制》的课后参考模型，对于学习电力电子变频器模型预测控制有很大的帮助。

利用matlab进行视频中的图片按帧数截取并且保存，其中包含了路径，也可以对其进行修改，本人利用此代码主要用来做卷积神经网络的的训练集图像的截取。。

基于MATLAB的人脸眼睛嘴巴检测，内涵说明书，摘要，代码等，同时含有自制神经网络训练集的代码（用户运行代码做出表情代码自动归类训练集合），主代码通过先检测脸部特征，后综合检测眼睛张开关闭+嘴巴张开关闭判定人脸是否处在疲劳状态，代码本人已经调试运行无误。
