This set of Matlab (7.0) functions contain the core code for generating Fig.2 and Figs.4(a,b) of the following paper: "Bayesian Compressive Sensing" Shihao Ji, Ya Xue, and Lawrence Carin, IEEE Trans. Signal Processing, vol. 56, no. 6, June 2008. and Fig.2 and Fig.3 of the following paper: "Multi-Task Compressive Sensing" Shihao Ji, David Dunson, and Lawrence Carin, IEEE Trans. Signal Processing (Accepted), 2008. -------- BCS_demo -------- 1) Fig2.m ---> generate Fig.2 The following two Matlab files from l1-magic are required for BP implementation: l1qc_logbarrier.m l1qc_newton.m which can be found at: http://www.acm.caltech.edu/l1magic/ 2) Fig4_ab.m ---> generate Figs.4(a,b) multi_random_measures.m ----> generate the "Random" curve for Fig.4a multi_optimized_measures.m ----> generate the "Optimized" curve for Fig.4a multi_approx_measures.m ----> generate the "Approx." curve for Fig.4a ---------- MT_CS_demo ---------- ***A bug was fixed on Aug. 03, 2008 in MT_CS.m for the cases where signals are dramatic undersampled.*** 1) Fig2.m ---> generate Fig.2 2) Fig3.m ---> generate Fig.3 multi_runs_75.m ----> generate the "MT 75%" curve for Fig.3 multi_runs_50.m ----> generate the "MT 50%" curve for Fig.3 multi_runs_25.m ----> generate the "MT 25%" curve for Fig.3 The code is still in development stage. If you have any comments or bug reports, you are welcome to contact Shihao Ji at shji@ece.duke.edu. Please check back at http://www.ece.duke.edu/~shji/BCS.html for updates.
