CS: T-SBL/T-MSBL Codes available

Zhilin Zhang sent me the following e-mail about the T-SBL/T-MSBL algorithms featured in [1], [2] and [3]:

Hi, Igor,
How are you! I finally finished the code-writing job. Now the codes of T-SBL/T-MSBL are available and can be downloaded from the link:
For reproducibility, it includes some demos which can re-produce the experiment results in my paper.
I also post the code of tMFOCUSS (developed in my ICASSP 2011 paper) in my homepage. It can be downloaded from the link:
Also, I wrote a new version of the MSBL code, which can be downloaded from here:
Although our lab alumni, David, posted his code in his homepage, that code is not suitable for algorithm comparison in most cases (since the values of some parameters are not suitable). The new version has chosen better values for these parameters and added many comments and advices.
I'll very appreciate if you can mention these codes via your blog and add them into the code collection.

Best regards,
Zhilin  noticed that the algorithms were to cumbersome to use with parameter tuning, so he spent the week-end rewriting part of the algorithms. Here is his new entry on the subject on his blog:  New Versions of T-MSBL/T-SBL are Available for Download that features the new codes.

Thanks Zhilin , I'll feature your code soon on the reconstruction section of the Big Picture in Compressive Sensing.
