"""SPGL1 is a solver for large-scale one-norm regularized least squares. It is
designed to solve any of the following three problems: Basis pursuit denoise
(BPDN): minimize ||x||_1 subject to ||Ax - b||_2 <= sigma, Basis pursuit (BP):
minimize ||x||_1 subject to Ax = b Lasso: minimize ||Ax - b||_2 subject to
||x||_1 <= tau, The matrix A can be defined explicitly, or as an operator that
returns both both Ax and A'b. SPGL1 can solve these three problems in both
the real and complex domains."""
