正则化工具包Hansen2008_Regularization Tools, A Matlab Package for Analysis and Solution of Discrete ill-posed Problems-Hansen2008_Regularization Tools, A Matlab Package for Analysis and Solution of Discrete ill-posed Problems

正则化的目的：防止过拟合；正则化的本质：约束（限制）要优化的参数。(Regularization purpose: to prevent overfitting! the nature of regularization: constraints (constraints) to optimize parameters.)
