Generates a lognormally faded signal with multipaths (10) and multiple scattering (5)

sar图像处理,合成孔径雷达成像及处理，有matlab程序(sar image processing, synthetic aperture radar imaging and processing, there are matlab program)

matlab函数scaleif，用于改变度量，详见英文描述( function sim = scaleif(im, newMin, newMax, oldMin, oldMax) Scales an image such that its lowest value attains newMin and it highest value attains newMax. OldMin and oldMax are not necessary but are useful when you don t want to use the true min or max value.)

在线极限学习机函数，包含拟合和分类功能，有详细注释(Extreme Learning Machine function includes fitting and classification, detailed notes)

用此方法拟合椭圆，方法简单，运算量较小，很适合计算机变成实现。(fast ellipse fitting)

说明：  在新材料制备过程中，会遇到大贡的实脸数据需要处理的问题，利用visualBasic6.0调用Matlab可解 决这一问题。介绍了基本原理，执行办法，以及曲线拟合的理论方法，并给出了实现的程序和编制软件的部分界面。 (Abstract The preparation process of the new materials will meet the real face great tribute to deal with the problem of data, using visualBasic6.0 call Matlab solve this problem. Introduced the basic principles, implementation, and the theoretical curve fitting method, and gives the implementation process and the preparation of some of the software interface.)
