解L1正则化回归问题（lasso）的Lars算法 -a classic algorithm for lasso called LARs——Least Angle Regression

稀疏建模工具箱，是一个为解决各种稀疏估计问题的开源优化工具箱，可实现字典学习与矩阵分解；使用LARS、快速下降法、OMP、SOMP等算法解决稀疏分解问题；使用Lasso解决结构化稀疏分解问题- Dictionary learning and matrix factorization Solving sparse decomposition problems with LARS, coordinate descent, OMP, SOMP, proximal methods Solving str

最小角度回归分步算法（LARS）,是稀疏表示求解中常用的算法-LARS is a commonly used algorithm for sparse representation

Lars算法在MATLAB中的实现，也可以通过选择参数来做lasso(The implementation of the Lars algorithm in MATLAB can also be used to do lasso by selecting parameters)
