说明：  利用C#创建窗体，通过设置按钮，同时利用按钮实现各种功能。此代码实现的功能是1、调用函数；2、显示照片，同时还能消除照片；3、通过调用MATLAB，实现图像显示的函数。(Use C# to create a form, by setting the button using the button at the same time to achieve various functions. This code implements the function is 1, call the function 2, display photos, while eliminating photographs 3, by calling MATLAB, the function of image display.)

室内实时定位系统两地算法TWR和对称两地算法SDS-TWR的误差分析，得出SDS-TWR大大提高精度(Both indoor RTLS algorithm and symmetric two TWR SDS-TWR algorithm error analysis, the SDS-TWR greatly improved accuracy)

如何用matlab计算微分方程，讲的很详细，并且赋有源码和测试结果，运行通过！(How to calculate differential equations with matlab, said very detailed, and are endowed with source code and test results, run through!)

有限元求解结构固有频率和振型、显示（中心差分法，Newmark法）、隐式法、非线性法程序(middle difference/Newmark/nonlinear)

优化问题是工业设计中经常遇到的问题,许多问题最后都可以归结为优化问题. 为了解决各种各样的优化问题,人们提出了许多优化算法,比较著名的有爬山法、遗传算法神经网络算法等. (Optimization problem is often encountered in industrial design, many problems can be attributed to the last optimization problem in order to solve a variety of optimization problems, many optimization algorithms have been proposed, relatively well-known climbing method, genetic algorithm neural network algorithm.)
