绘制二维坐标系的源码。且包含绘制sin(x)和cos(x)的例子。

这个Matlab程序使用eigenface系统实现人脸识别，它使用AT&T的数据库，运行代码实例前，请阅读其中的comment，下载该数据库。-Matlab program uses the eigenface face recognition system, which uses AT

一个cad程序 很好用的，希望对大家有用，-Cad program with a very good, and I hope useful for everyone,

在图形模式下显示3D图形绕任意轴旋转的程序，物体的每一个顶点的坐标都储存在外部变量point中了，比如说第一个顶点就是point[0],他的坐标是(point[0][0],point[0][1],point[0][2])。整个步骤我想在程序的注释中讲得很清楚了。-in graphic mode display 3D graphics rotating procedures objects each vertex of the coordinates are stored in the external variables which point, for instance, the first point is a vertex [0], the coordinates of (point [0] [0], [0] point [1] point [0] [2]). I think the whole process in the Notes procedures made very clear.

世界编程大赛作品“幽灵古堡”值得大家学习。-World Programming Contest entries "ghost castle" deserve study.

三维模型大多是用三角网格形式描述的，基于OpenGL和C++绘制了三角网格模型，并实现了与键盘和鼠标的交互，通过点击鼠标键和按键盘响应键，可以对模型进行旋转、缩放、移动等操作。

键盘控制芯片C语言控制程序，通过该程序可以实现7219芯片大部分LED控制功能的演示，以及键盘的读取，其中的I2C子函数也可以用于其他I2C器件-keyboard controller chip C language control procedures, the adoption of the 7219 procedures can be achieved most of LED chip control functions of the display, keyboard and read, I2C Functions can also be used for other I2C devices
