Optimization codes for sparsity related signal processing

File Information
Description

This toolbox contains the implementation of what I consider to be fundamental algorithms
for non-smooth convex optimization of structured functions. These algorithms might not be the fasted
(although they certainly are quite efficient), but they all have a simple implementation in term
of black boxes (gradient and proximal mappings, given as callbacks). However, you should have
some knowledge about what is a gradient operator and a proximal mapping in order to be able
to use this toolbox on your own problems. I suggest you have a look at the
"suggested readings" for some more information about all this.

Thanks very much

some files are lost such as Homotopie2.m
you'd better update your file.

it will be better if your zip contains a file of description

Is there any GUI associated with this?

Hi, Gabriel your work is really interesting.

Actually, I am working with unmixing techniques for images and I want to apply sparse positive matrix factorization. I find your code could be very useful to me but, I do not have clear how to use the code. Can you help me sending me maybe a readme file with more details. I am really excited to use these functions.
Thanks.

Hello Gabriel, Thanks very much for your code. But it will be better to provide a readme file with more detailed description.

Modified license.
Remove GPL files. Gabriel said he will redo this in January.
