Description: 最小化l1范数的Matlab代码。求解模型为：
min lambda*|x|_1+||A*x-y||_2。其中，|x|_1表示x的1-范数，||*||_2表示2-范数。该模型在稀疏成分分析、压缩传感器等领域有广泛的用途。- l1-Regularized Least Squares Problem Solver
l1_ls solves problems of the following form:
minimize ||A*x-y||^2+ lambda*sum|x_i|,
where A and y are problem data and x is variable (described below).
