matlab编写的俄罗斯方块，很简单，但很好玩(matlab prepared by the Russian box, very simple, but very fun)

本程序通过优化ICA算法实现了混合图像的盲源分离，分离效果优于一般ICA算法(This procedure optimized ICA algorithm is a mixed picture of blind source separation, separation is better than the general ICA algorithm is)

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.)

This function reads in lat/lon and brightness temperature from a mcidas area file, into Matlab.

将原图像用bior四层分解，之后弱化低频分量，重构原图，以得到细节。(use wavelet function(bior) to enhance the detail of the image,then reconstuct)

该代码描绘了服从正态阴影模型的路径损耗和自由空间的路径损耗。并且添加了阴影产生的随机效应。(The code depicts shading model subject to normal free-space path loss and the path loss. And add a shadow generated random effects.)
