线性四面体元的有限元分析可直接利用的函数，包括求刚度矩阵，求体积，求整体刚度矩阵等，有重要的利用价值(Linear tetrahedral element finite element analysis can be directly used for functions, including seeking stiffness matrix, the volume demand, the global stiffness matrix of such demand, there is significant value in use)

本程序源码是为日本一家地震监测机构编写的，用来演示地震对不同楼层的作用效果。可以手动调整震动幅度的比例。(the program source code is one of Japan's earthquake monitoring bodies to prepare, used to demonstrate the different floors of the earthquake in effect. Vibration can be manually adjusted rate ratio.)

异步电机矢量控制的原理图，用matlab建立了一部电机的模型，对矢量控制进行了仿真。(Schematics, vector control of induction motor using matlab model of a motor, vector control simulation.)

自编小程序，希望大家多多指导！！！！！！！小弟谢了(self small procedures in the hope that Members can guide! ! ! ! ! ! ! The younger Xie)

，建立车体6个自由度加上前轮转向系统1个自由度的汽车数学模型；该汽车数学模型不需引入很多的人为假设；可以实现给定汽汽车前轮转角，也可以不给定前轮转角；不依赖需要复杂测定的侧向力函数及相关模型参数；考虑了轮胎的滚动特性 已通过测试。 (Vehicle mathematical model of one degree of freedom, the establishment of the body' s six degrees of freedom coupled with front-wheel steering system mathematical model of the car does not need to introduce a lot of people assume front wheel angle can be achieved given steam can also be given front wheel angle does not depend on the complex determination of the lateral force function and model parameters consider rolling characteristics of the tire has been tested.)

布谷鸟算法是一种新的智能优化算法，广泛应用于工程问题。(Cuckoo algorithm is a new intelligent optimization algorithm, widely used in engineering problems.)

说明：  基于神经网络的PID源程序 可用于学习!!(PID based on neural networks can be used to study the source code!!)
