利用MATLAB编写的快速AEC算法，比传统的回声消除算法速度快很多。(A algorithm of acoustic echo cancellation (AEC) using MATLAB. It is faster than conventional AEC algorithm.)

Background Given a set of rectangles {R1, R2, …, Rn}, compute the area of their common intersection. i.e., Area(R1∩R2∩…∩Rn) The edges of the rectangles R1, R2, …, Rn, are either vertical or horizontal lines. For example, the intersection of 4 rectangles, R1, R2, R3, and R4, in the following figure is the shaded rectangle. Input The input contains (N + 1) lines. The first line specifies the number of rectangles N, where 1 < N < 1000. Since the sides of the rectangles are parallel to the x-axis and y-axis, each rectangle is bounded by the lines x = x1, x = x2, y = y1 and y = y2 and each subsequent line of the input file thus specifies one rectangle in the following format: x1 x2 y1 y2 such that 0 <= x1 < x2 <= 10000 and 0 <= y1 < y2 <= 10000, and x1, x2, y1 and y2 are integers. Output The output file contains the area of the intersection of all the rectangles.

赛车游戏VC源代码 编译RaceX.dsw文件，在Debug目录下会生成文件RaceX.exe，直接双击该文件，即可运行“赛车”程序。 ********** 要正确编译源代码，需要安装DirectX 8.0及其以上版本。-racing game VC source code compiler RaceX.dsw documents in the Debug directory will RaceX.exe file, double-click the file directly, and can run "car" procedures.********** To compiling the source code need to install DirectX version 8.0 and above.
