FPC: Fixed Point Continuation Copyright (C) 2007-2008 Elaine Hale, Wotao Yin and Yin Zhang ------------------------------------------------------------- 1. Introduction ================ Fixed-point continuation (FPC) is an algorithm for solving large-scale l-1 regularized least-squares problems min_x ||x||_1 + (mu/2)*||Ax - b||_M^2 using fixed-point iterations paired with a continuation strategy for mu. 2. Getting Started =================== The files in the drivers folder generate example compressed sensing problems and solve them with fpc.m or fpc_bb.m. To run them, set your current directory to .../fpc/drivers, and call bb_run or basic_run from the command line. The files automatically add the appropriate folders to your Matlab path (temporarily). Note that some of the example problem types (determined by Ameth) require the signal processing toolbox. 3. Optional External Packages ============================== FPC is compatible with the SPARCO toolbox, which contains a number of problems for benchmarking sparse reconstruction algorithms, along with a library of linear operators that can be used to generate additional problems.
