A recursive approach for shrinking coefficients of an atomic decomposition is
proposed. The corresponding algorithm evolves so as to provide at each
iteration a) the orthogonal projection of a signal onto a reduced subspace and
b) the index of the coefficient to be disregarded in order to construct a
coarser approximation minimizing the norm of the residual error.
