candes提出来的一种应用在CS上的重建算法-NESTA:AFASTANDACCURATEFIRST-ORDERMETHOD FORSPARSERECOVERY

NESTA，非常好的优化算法,The algorithm uses two ideas due to Yurii Nesterov. The first idea is an accelerated convergence scheme for first-order methods, giving the optimal convergence rate for this class of problems. The second idea is a smoothing technique t

Block nesta for recovery sparsity.
