%    "Atomic Decomposition by Basis Pursuit"
% by S. Chen, D. L. Donoho and M. A. Saunders.
% See http://www-stat.stanford.edu/~atomizer
%
% The paper proposes the Basis Pursuit principle for atomic
% decomposition in overcomplete dictionaries.  Basis pursuit
% chooses the "optimal" representation by minimizing the
% $l^1$ norm of coefficients.  The paper gives examples to
% show that Basis Pursuit has some advantages over the
% Method of Frames, Matching Pursuit, and the Best Orthogonal Basis
% method, including better sparsity and super-resolution.

% Many figures here are identical to the ones in Scripts/Thesis
