L-曲线法是反问题正则化方法中的参数选取中的重要方法，本程序给出了如何恰当选取其中的参数！-L-curve method is the inverse problem regularization method of parameter selection in an important way, this procedure is given on how to properly select one of the parameters!

反演问题中正则化参数阿尔法的l-curve选取方法，用于画出l-curve，选取曲率最大的点。-Inverse problem regularization parameter alpha l-curve selection method used to draw l-curve, the point of maximum curvature.

压缩包里包含了：正则化方法，L曲线，奇异值分解等，希望对大家有帮助(Compression package contains: regularization method, L curve, singular value decomposition and so on, we hope to help everyone.)
