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.)

erpPCA可用于特征提取，是对pca的优化(erpPCA can be used for feature extraction, is to optimize the pca)

MATLAB内部函数小改动，可实现一些算法(MATLAB internal function of small changes, some algorithms can be realized)

说明：  Matlab7.0的Kohonen的SOFM(自组织特征映射)源程序(Matlab7.0 of Kohonen' s SOFM (self-organizing feature map) source)

通过在matlab平台上运行这个程序，可以画出一个生动的玫瑰花，赶快把你的女朋友或者心仪的女生叫到电脑旁边给她一个惊喜吧。(this source code can help you show your love to somegirl by giving a wonderful rose plot.)
