The application is from aerospace structures, aerodynamics, dynamics and control, and aerospace systems selected. The technologies include: numerical integration of ordinary differential equations systems partial differential equations of finite difference, finite volume, and finite element discretization numerical linear algebra eigenvalue problems with constraints and optimization.)

TC环境下C语言实现的类似于matlab的数字信号和数字系统分析。使用图形界面，具有坐标显示。可以有z变换后的系统函数直接分析系统的幅频和相频响应(TC C language environment similar to matlab digital signal and digital systems analysis. Use graphical interface, with coordinates display. Z-transform can be directly after the system function of the amplitude-frequency analysis system and phase-frequency response)

模拟退火算法及MATLAB程序代码,包含算法pdf文档，PPT讲义和M文件。(Simulated annealing algorithm and MATLAB code that contains the algorithm pdf documents, PPT handouts and M files.)

说明：  资料为基于BP基于BP神经网络的人脸识别源码（matlab），是课程设计做的一个课题，效果还不错，配备有测试显示界面，比较直观！(The data is the source code of face recognition based on BP neural network (matlab), which is a subject of curriculum design. The effect is good, equipped with test display interface, which is more intuitive!)

说明：  Matlab code for knapsack

学校电子设计竞赛时做的一个小DDS系统,功能较全,基于DSPBuilder,在MatLab R2009b中仿真通过(Electronic Design Competition when schools do a small DDS system function than the whole, based on DSPBuilder, in the simulation in MatLab R2009b by)

利用Matlab软件工具，对简单的植被形态进行模拟，模拟结果生动逼真。首先，迭代产生一系列字符串；其次，根据将L系统与图形联系起来，采用龟形的概念赋予每个字符特定的图形含义；最后，读取字符并画图，根据读取到的字符通过Matlab实现相应的操作。(According to L system and iterated algorithm, shape of trees were simulated with matlab functions and programs and the fractal trees’ configurations were natural and living. First, we use iteration to produce a series of string. Then, connecting the L system with graphs, we use the theory of turtles to give each character a specific meaning. Finally, read the string and draw pictures with the matlab. )

说明：  完成给定的两幅图像中差异之处寻找。显示出两幅图中哪里经过了篡改(Find the difference between the two images. Shows where the two images have been tampered with)
