一个报童从报刊发行中心订报后零售，每卖一份报纸可赚钱a元；若报纸卖不出去，则退回发行处，每退一份要赔钱b元。每天报童卖出的份数是随机的，但报童可以根据以往卖报情况统计得到每天卖k份报纸的概率密度p(k)。 （1） 求报童每天期望收益达到最大（或损失达到最小）的定报量z。 （2） 改变参数a/b的值，观察订报量的最优值变化，画出变化曲线。 试画出仿真流程图，进行程序实现，并对仿真结果进行分析。 (A newsboy subscribe from the press after the retail distribution centers, each sale of a newspaper can make money a million if newspapers can not be sold, then returned to Issue Department, each retire to a loss of a b element. Newsboy sold shares in a day is random, but the newsboy can sell based on past statistics reported to be selling daily newspaper k the probability density p (k). (1) seeking newsboy expected profit per day to maximize (or minimize loss) reported that the volume of fixed-z. (2) change the parameters a/b values, subscribe to observe changes in the volume of the optimal value, draw curve. Simulation test to draw a flow chart for program realization, and simulation results for analysis.)

产生均匀分布的随机白噪信号,并观察数据分布的直方图产生均匀分布的随机白噪信号,并观察数据分布的直方图(Generate uniformly distributed random white noise signal, and to observe the distribution of the histogram data generated uniformly distributed random white noise signal, and to observe the data distribution histogram)

说明：  matlab的图像融合，,图像融合时可以参考(Matlab image fusion, and image fusion can reference)

用matlab编写的小波去噪程序，其中还包括自编的阈值去噪程序。是改进过的。(Two-dimensional wavelet denoising procedure using matlab，Which also includes the self threshold denoising procedure ，improved！)

在科学与工程计算中，最小二乘法用来拟合数据，精度很高。(Scientific and Engineering Computing, the least squares method is used to fit the data to high precision.)
