Greedy Algorithms promoting Group Sparsity

24 Jan 2009

Approximate Greedy Solutions to the problem min||x(k)||_2,0 such that Ax = b

File Information
Description	BOMP - Block Orthogonal Matching Pursuit Proposed by Eldar & Bolcskei GOMP - Group Orthogonal Matching Pursuit Differeing from BOMP in the way, sparse group is chosen StGOMP - Stagewise Group Orthogonal Matching Pursuit Combining ideas from StOMP and BOMP. Selects multiple groups simultaneously. ReGOMP - Regularized Group Orthogonal Matching Pursuit Combining ROMP and GOMP.
Acknowledgements	This submission has inspired the following: Greedy Algorithms promoting Group Sparsity V2
MATLAB release	MATLAB 7.4 (R2007a)
