实际的场景，若电梯的最大载客量m=10，设电梯中已有的 客人服从0-10 之间的均匀分布，且电梯中的任意一人在任意一层下的 概率相同，若你在第三层需要乘电梯到第七层，电梯处在第一层，共 8 层。且在每一层等电梯到达他们的目的楼层的客人服从0-3 的均匀分 布此时我们对电梯的运行加一些限 制，即电梯中若有客人未达目的地，电梯不会改变运行方向，求直到 你到达第七层为止，，电梯需停次数的数学期望，并进行计算机模拟验 证。(The actual scene, if the maximum lift capacity m = 10, the elevator has been designed to obey the guests uniformly distributed between 0-10, and the elevator in any one at any level under the same probability, if you The third layer needs to take the elevator to the seventh floor, the elevator in the first layer, a total of 8 layers. And in each level to reach their goals such as the elevator floor guests subject to the uniform distribution of 0-3 at this time we add some restrictions on the operation of the elevator, the elevator if it has not reached the destination guests, the lift will not change the direction, request until you reach the seventh floor so far, the elevator number of mathematical expectation to be stopped, and the computer simulation.)

ISAR 成像时利用多普勒中心法进行相位补偿的matlab程序(Doppler phase compasation)

压缩包里面有四个函数，实现了常用的几种模糊聚类方法，附有较详细的注释(There are four functions in the file. these functions fulfills common method of fuzzy cluster. Commments are quite good)

说明：  （2,1,7）归零卷积码的维特比译码算法的matlab实现((2,1,7) convolutional codeviterbi algorithm matlab implementation)

说明：  无网格法求解2维悬臂梁问题的Matlab程序，与有限元方法相比有很大的好处(the method of meshless)

本程序仿真了正交频分复用的调制与发射，其中包括循环前缀，FFT变换，白噪声信道模拟等部分，最后得出不同信噪比先的系统误码率。(This program simulates the orthogonal frequency division multiplexing modulation with the launch, including the cyclic prefix, FFT, white noise channel analog part of the conclusion that a different signal to noise ratio before the BER.)
