YALL1-Group: A solver for group/joint sparse reconstruction
From Wikimization
YALL1-Group is a MATLAB software package for group/joint sparse reconstruction, written by Wei Deng, Wotao Yin and Yin Zhang at Rice University.
Model
(1) Group-sparse basis pursuit model:
Minimize subject to
where , , denotes the index set of the -th group, and is the weight for the -th group.
(2) Jointly-sparse basis pursuit model:
Minimize subject to
where , denotes the -th row of matrix , and is the weight for the -th row.
Syntax
- [x,Out] = YALL1_group(A,b,groups,varargin);
