报童问题(负指数分布)
几个参数:
卖出报纸挣a元,退回报纸赔b元
卖报量y,订报量z,订报量上限z_up
观察期的总天数t,用于积累天数的ti
总的平均损失量ave_loss,供过于求损失loss1,供小于求损失loss2,ave_loss=loss1+loss2
最佳订报量superz,最小损失量ave_loss_min (newsvender)

Data-processing
基于FFT的功率谱分析程序设计与应用
2)对实验所采集的转子振动信号进行频谱分析
2.讨论:
1) 信号经过均值化处理或不经过均值化处理的结果比较
2)采用不同窗函数时的谱结果(矩形窗函数, 汉宁窗函数,汉明窗)
3)典型函数的频谱(矩形窗函数, 汉宁窗函数,直线,阶跃函数,δ函数,方波,三角波等)
4)整周期和非整周期采样时两者的比较
5)讨论实验结果
(Based on the FFT power spectrum analysis of program design and Application2) on experimental collection of the rotor vibration signal spectrum analysis2 discussion:1) the signal through the mean treatment or not after a mean treatment results comparison2) using different window function spectral results ( rectangle window, Hanning window function, the Hamming window )3) the typical functions of spectrum ( rectangle window, Hanning window function, linear, step function, function, square wave, triangular wave)4) the whole cycle and non-integer-period sampling time comparison5) discussion of experimental results)

实验2-插值与拟合
1、掌握用MATLAB计算拉格朗日、分段线性、三次样条三种插值的方法,改变节点的数目,对三种插值结果进行初步分析。 2、掌握用MATLAB作线性最小二乘的方法。 3、通过实例学习如何用插值方法与拟合方法解决实际问题,注意二者的联系和区别。(1. Grasp by matlab calculating Lagrange, segement linear, 3rd order spline these 3 interpolation method. Analisize the 3 interpolation results by changing the No. of points.
2. Grasp the method of linear minimun 2 product mehtod using matlab.
3. Solve the practical problems though the study of example of how to use interpolation and fitting method. Pay attention to the relation and difference of the 2 methods.)
