Preprint available at http://arxiv.org/abs/1204.0562 The algorithm is implemented in ast_denoise.m and scripts in the subfolder backends. For usage details, type help astlinespec in the MATLAB prompt. The code also redistributes SpaRSA script for solving the Lasso problem (See http://www.lx.it.pt/~mtf/SpaRSA/) and the CVX and SDPT3 packages for semidefinite programming available at http://cvxr.com and http://www.math.nus.edu.sg/~mattohkc/sdpt3.html
