借助MATLAB软件的绘图功能，对函数的特性进行探讨，广泛联想，大胆猜想，发现进而证实其中的规律。(Braking distance )

几种常用分布（如泊松分布、正态分布、指数分布、均匀分布）随机变量的matlab实现方法。(Surement distribution (eg Poisson distribution, normal distribution, exponential distribution, uniform distribution) random variable matlab implementation methods.)

说明：  反距离权重法主要依赖于反距离的幂值，幂参数可基于距输出点的距离来控制已知点对内插值的影响。(The inverse distance weight method mainly depends on the power value of the inverse distance, and the power parameter can control the influence of known points on the interpolation based on the distance from the output point.)

1,某厂向用户提供发动机，合同规定，第一、二、三季度末分别交货40台、60台、80台．每季度的生产费用为 f=ax+bx^2（元），其中x是该季生产的台数．若交货后有剩余，可用于下季度交货，但需支付存储费，每台每季度c元．已知工厂每季度最大生产能力为100台，第一季度开始时无存货，设a=50、b=0.2、c=4，问工厂应如何安排生产计划，才能既满足合同又使总费用最低． 2,函数的输入为A,B两个矩阵，实现如下功能：从A矩阵中找出与B完全相同的子矩阵，并将该子矩阵左上角的位置保存到2*n的向量index中，最后函数返回A中所有与B完全相同的子矩阵的左上角坐标。(1, a factory to provide users with the engine, the provisions of the contract, first, second and third quarter, respectively Delivery 40 units, 60 units, 80 units. The production cost of each quarter the f = ax+bx ^ 2 ($), where x is the number of Taiwan-quarter production. If after delivery, the surplus can be used for delivery next quarter, but to pay the storage fees, each quarterly c. Factory known each quarter of the maximum production capacity of 100 units of stock in the first quarter, setting a = 50, b = 0.2, c = 4, asked how the factory should arrange production plan, in order to both meet the contract and the lowest total cost of . 2, the function' s input is the two matrices A, B, to achieve the following functions: to identify from the matrix A and B are identical sub-matrix, and a position in the upper-left corner of the sub-matrix is ​ ​ saved to the vector index of 2* n, The last function returns the coordinates of the upper left corner of the sub-matrices A)
