碎纸片的拼接复原算法及MATLAB实现

航空发动机JT9D模型，可用于航空发动机建模以及控制(JT9D Model of Aeroengine)

说明：  MTCNN，Multi-task convolutional neural network（多任务卷积神经网络），将人脸区域检测与人脸关键点检测放在了一起，它的主题框架类似于cascade。总体可分为P-Net、R-Net、和O-Net三层网络结构。(MTCNN, Multi-task convolutional neural network (multi-task convolutional neural network), puts face region detection and key point detection together, and its subject framework is similar to cascade. Overall, it can be divided into three layers: P-Net, R-Net and O-Net.)

PQ分解法，有些还需要改进，该程序所对应的例子是东南大学陈珩编的《电力系统稳态分析（第二版）》的例4-5(PQ decomposition, some also needs to be improved, The procedure corresponding to the example of Southeast University, Chen Heng addendum to the "steady-state power system analysis (second edition)" 4-5 cases)

说明：  有问题联系我，驱动小车，l298n，stm32f103zet6，(Contact me if you have any questions. Drive the car, l298n, stm32f103zet6.)

说明：  卷积神经网络实现手势数字的识别（基于tensorflow）(Recognition of gesture numbers by convolutional neural network (based on tensorflow))

包括贪吃蛇，俄罗斯方块，扫雷，推箱子，连连看，拼图六款小游戏代码(Including the Snake, the Russian box, mine clearance, Sokoban, Lianliankan, six puzzle game code)
