这是一个由我本人亲自编写的提取图像特定部分的MATLAB程序。通过使用这个函数，你可以轻而易举地将图像的特定位置用白色矩形线框加以圈定、显示。(If you want to circle the specific area of an image, this little program is much more practical and convenient, thus will help you to mark any area of the image with with rectangle.)

本人用matlab编写的rels(最小二乘法），rls(递推增广最小二乘法),riv(辅助变量法递推算法)的程序，都是2阶的，稍改动就可以变成其它阶次(I use matlab prepared rels (least squares), rls (augmented recursive least squares method), riv (auxiliary variable method recursive algorithm) procedure, are 2 bands, a little change can be turned into other order)
