This view allows us to significantly simplify the recovery analysis of compressive sensing. More importantly, it leads to an efficient optimization algorithm for solving the regularized optimization problem related to the sparse recovery problem. Compared to the existing approaches, there are two advantages of the proposed algorithm. First, it enjoys a geometric convergence rate and therefore is computationally efficient.
