You will need the MATLAB L1-MAGIC toolbox for solving the convex 30 | optimization programs central to compressive sampling. 31 | 32 | 1. Put the contents of the CS Recovery Algorithms toolbox somewhere (say, 33 | $HOME/matlab/). 34 | 35 | 2. Add the new directories to your path permanently; e.g., add the 36 | following to your startup.m: 37 | addpath ~/matlab/CS Recovery Algorithms; 38 | 39 | Basic command reference 40 | ------------------------ 41 | 1.
