说明：  以悬臂梁为例，用有限元法编程生成质量矩阵和刚度矩阵（采用平面梁单元，单元数在10到30之间）。 使用matlab的用于广义特征值问题分析的函数（eig(A,B,'chol')，该命令使用乔莱斯基分解的方法，计算对称矩阵A和对称正定矩阵B的广义特征值问题。A对应刚度矩阵，B对应质量矩阵）计算梁的前三阶固有频率和振型，计算得到梁的前三阶固有频率和振型，并画出振型图。(Taking cantilever beam as an example, the mass matrix and stiffness matrix are programmed by finite element method (using planar beam elements, with units ranging from 10 to 30). Using Matlab's function (eig (A, B,'chol') for the generalized eigenvalue problem analysis, the command uses the Jo Lessky decomposition method to calculate the generalized eigenvalue problem of the symmetric matrix A and the symmetric positive definite matrix B. A corresponds to the stiffness matrix and B corresponding to the mass matrix. The first three natural frequencies and modes of the beam are calculated, and the first three natural frequencies and modes of the beams are calculated, and the vibration pattern is drawn.)

贪吃蛇2005 + 源程序　 贪吃蛇 一个经典的小游戏，本人精心制作，相信会比其它所谓的贪吃蛇效果好很多。希望大家能提出更多宝贵的意见。游戏规则： 利用方向键控制蛇头运动，当蛇头碰到食物即吃到食物，获得积分； 在此过程中不允许蛇头出界或碰到身体，否则游戏结束。基本操作： 程序运行后输入数字0-9，选择级别；任何时候按Esc键即退出游戏；用键盘方向键控制蛇头运动方向；按任意键暂停，方向键和组合键除外；暂停后，按方向键继续游戏；出错后会出现是否继续游戏的提示，Y继续，N结束。 -2005 Snake Snake source of a small classic game, I carefully made, I believe other than the so-called Snake many good results. Hope we can put forward more valuable suggestions. The rules of the game : direction control keys snakeheads campaign, when the food is encountered snakeheads eat food, access points; In this process does not allow out-of-bounds snakeheads or physical encounter, the end of the game. Basic operation : running after importation figures 0-9, choose level; By any time that the Esc keys out of the game; The keyboard keys to control the direction snakeheads movement direction; Keys suspended by the arbitrary direction keys and key combinations exception; Following the suspension, according to the direction keys to th

这是我的第一个小学期程序设计的程序，个人通信录，是在VC++环境下开发的，虽然比较简单，但是体现了VC的实用性和可视性。-This is my first one primary phase of the program design process, personal communication, for the VC environment is under development, Although it is quite simple, but reflects the VC practicality and visibility.

说明：  介绍main函数的执行动作和入口形式。先是配置中断向量，再是配置时钟，然后是配置GPIO、串口等外设。(This paper introduces the execution action and entry form of main function. Firstly, the interrupt vector is configured, then the clock is configured, and then the peripherals such as GPIO and serial port are configured.)
