08 Sep 2009 Non Convex Compressed Sensing for Non Gaussian Noise optimization of the form min ||x||_p subject to ||y-Ax||_q<e Author: Angshul Majumdar

itecheck has something to do with the version of Matlab you are using. U can search the iterchk function online from google and add it to your Matlab Path.
06 Apr 2009 Complex step Jacobian Calculate Jacobian using complex step differentiation Author: Yi Cao

the step size 'eps' is not specified? Do U suggest a value?
20 Feb 2009 FLD-based Face Recognition System This package implements 'Fisherface', a FLD-based face recognition system. Author: Amir Omidvarnia

Works well for the toy example provided. Should have been more general.
29 Jan 2009 Greedy Algorithms promoting Group Sparsity Approximate Greedy Solutions to the problem min||x(k)||_2,0 such that Ax = b Author: Angshul Majumdar
29 Jan 2009 Orthogonal Least Squares Algorithms for Sparse Signal Reconstruction Greedy Algorithms for Underdetermined but Sparse Solutions Author: Angshul Majumdar

07 Sep 2011 Orthogonal Least Squares Algorithms for Sparse Signal Reconstruction Greedy Algorithms for Underdetermined but Sparse Solutions Author: Angshul Majumdar yunhua

it makes great sense
04 Sep 2011 Orthogonal Least Squares Algorithms for Sparse Signal Reconstruction Greedy Algorithms for Underdetermined but Sparse Solutions Author: Angshul Majumdar Zhao
18 Jul 2011 Generalized Principal Component Pursuit min nuclear_norm(L) + beta*||W(S)||_1 subject to ||y-F(S+L)|_2 < err Author: Angshul Majumdar Xuande, Zhang

great!!
