把稀疏度为4的信号，用OMP算法重构信号，然后比较重构的效果-design information

对窄带信号进行临界采样，采用重构算法恢复原信号-sample the narrowband signal and reconstruct signal

基于压缩感知理论的图像重构算法matlab实现，其中包含OMP，BP,IHT等重构算法-Reconstruction Algorithm Based on the theory of compressed sensing image reconstruction algorithm matlab implementation, which contains the OMP, BP, IHT, etc
