说明：  一楼房的后面是一个很大的花园. 在花园中紧靠着楼房有一个温室,温室伸入花园2m,高3m,温室正上方是楼房的窗台. 清洁工打扫窗台周围,他得用梯子越过温室,一头放在花园中,一头靠在楼房的墙上. 因为温室是不能承受梯子压力的,所以梯子太短是不行的. 现清洁工只有一架7m长的梯子, 你认为它能达到要求吗? 能满足要求的梯子的最小长度为多少?(The back of a building is a big garden. In the garden close to a building in a greenhouse, greenhouse into the garden 2m, high-3m, the greenhouse is the top of the building' s bay windows. Cleaners cleaning around the windowsill, he crossed to use a ladder greenhouse, on a garden, against a building wall. because of the greenhouse can not bear the pressure of a ladder, so the ladder is not too short. cleaners are only a 7m long ladder, do you think it can meet the requirement it? ladder to meet the requirements of the minimum length of the number?)

码分多址，是在无线通讯上使用的技术，CDMA 允许所有的使用者同时使用全部频带(1.2288Mhz)的系统仿真(CDMA is used in wireless communications technology, CDMA allows all users to simultaneously use all bands (1.2288Mhz) System Simulation)

模拟仿真蒙塔卡罗寻找中值,用此程序可以仿真中值的寻找结果.挺好的一个程序，有实用价值(simulation MonteCarlo finding meium value)

变频调速系统仿真搭建模型 由于观测仿真波形 记录以及分析实验结果(Variable speed control system simulation build the observation model simulation and analysis of experimental results wave record )

用matlab实现LMS自适应算法，20阶的fir滤波器，自适应效果非常好。(Matlab LMS adaptive algorithm, two order of fir filter, the adaptive effect is very good.)

在Matlab simulink环境下编写的在滑模控制模型的四分之一车模型。 经仿真效果很好(In Matlab simulink environment written in the quarter-car model sliding mode control model. The simulation works well)

2007年全国大学生数学建模获奖论文所需程序代码，其中有较详细的matlab编程，应该有些用处吧(Mathematical Contest in Modeling 2007, papers required for award-winning code, including more detailed matlab programming, it should be of some use)
