说明：  2005年电力部数学建模大赛题目： 共有61个比赛项目，1050人参加比赛。请给出算法及其框图，同时给出合理的比赛项目排序表，使连续参加两项比赛的运动员人次尽可能的少；表中“＃”号位置表示运动员参加此项比赛。建立此问题的数学模型，并且合理安排比赛项目顺序，使连续参加两项比赛的运动员人次尽可能的少；程序使用了最小生成树算法。(2005 Mathematical Modeling Contest subject : a total of 61 events, 1,050 people participate in the competition. Please give algorithm and its frame, the event is a reasonable ranking table to enable participation in two consecutive games of 000 athletes as less; Table "#" locations athletes this game. This established the mathematical model, and reasonable arrangements event sequence, and allows the two consecutive games of 000 athletes as less; Procedures for the use of the minimum spanning tree algorithm.)

无刷直流电动机矢量控制模型,控制IGBT而改变输入的.(The vector control model of Brushless DC Motor. Brushless DC Motor drived by IGBT)

Program to use your camera as a scanner. Automatically detects the page on the picture. (Description Useful program if you don t have a scanner or need to scan quickly a lot of pages. It detects the page on the picture, make it rectangular, cut the borders and enhance the contrast. Function parameters are the input picture filename and output filename. Some parameters that can be changed are described in the function. Be careful with the flash of the camera, it creates a non-homogeneous luminosity difficult to clean. Required Products Image Processing Toolbox MATLAB release MATLAB 7.5 (R2007b) )

利用newmark法求动力响应的程序，可以参考(Newmark method for the dynamic response of the program)

该算法是修正过的牛顿拉夫逊潮流算法 运用到matlab环境中可以直接输入原始参数运行(The algorithm is a modified Newton Raphson power flow algorithm can be applied to the matlab environment to run directly into the original parameters)
