压缩感知重构算法之压缩采样匹配追踪（CoSaMP）算法matlab程序，CoSaMP也是对OMP的一种改进，每次迭代选择多个原子，除了原子的选择标准之外，它有一点不同于OMP：ROMP每次迭代已经选择的原子会一直保留，而coSaMP每次迭代选择的原子在下次迭代中可能会被抛弃。-Compressed sensing reconstruction algorithm compression sampling of Matching Pursuit (CoSaMP) algorithm matlab program, CoSaMP also an improvement of OMP, each iteration　more than one atom, in addition to the selection criteria atoms, it s a bit different　the OMP: ROMP each iteration has been selected atom will remain, and each iteration coSaMP selected atoms in the next iteration may be abandoned.
