中文说明：MP算法(正交匹配追踪算法)作为对信号进行稀疏分解的方法之一，将信号在完备字典库上进行分解。OMP算法的改进之处在于：在分解的每一步对所选择的全部原子进行正交化处理，这使得在精度要求相同的情况下，OMP算法的收敛速度更快。
English Description：
MP algorithm (orthogonal matching pursuit algorithm) is one of the sparse decomposition methods of signal, which decomposes the signal on the complete dictionary. The improvement of OMP algorithm is that all the selected atoms are orthogonalized at each step of decomposition, which makes the OMP algorithm converge faster under the same precision requirement.
