- If you are using the old version 0.3 of the UNLocBox and upgrade to the newest version, please read this document. It takes 3 minutes, but will save hours.
This site contains a brief description of the convex optimization, as well as the MATLAB toolbox implementing the main algorithms.
Summary of the UnlocBox algorithms are in the following papers
"Proximal Splitting Methods in Signal Processing"
Patrick L. Combettes, Jean-Christophe Pesquet
Fixed-Point algorithms for inverse problems in science and engineering.
A version of the paper is also available on arxiv.

To be able to run the demos, you need different toolboxes:- The RiceWavelet Toolbox (For some image reconstruction demo): Download it here
- The LTFAT toolbox (For sound demo): Download it here
- The SPGL 1 toolbox (For the one projector): Download it here
- The Spectral Graph Wavelets Toolbox (For graph reconstruction demo): Download it here
