L1Packv2: A Mathematica package for minimizing an ℓ 1 -penalized functional

Description

Abstract L1Packv2 is a Mathematica package that contains a number of algorithms that can be used for the minimization of an ℓ_1 -penalized least squares functional. The algorithms can handle a mix of penalized and unpenalized variables. Several instructive examples are given. Also, an implementation that yields an exact output whenever exact data are given is provided.
