近完美重构多相滤波器组实例，包含分析滤波器，综合滤波器，其中原型滤波器系数可调整，以及重构错误的仿真。-Near perfect reconstruction polyphase filter example, contains analysis filters, synthesis filters, which can adjust the prototype filter coefficients, and the reconstruction error is simulated.

matlab OMP程序，先得到稀疏信号，再投影重构-Matlab OMP, first get sparse signal, and then the projection reconstruction

使用LSD，即对数倒谱距离（Log_Spectral_Distance）来评判重构出来信号与原始信号之间的差异。(It uses the Log_Spectral_Distance to judge the difference between the original signal and the restructed signal.)

模拟空间多孔介质,用matlab三维曲面重构。(The porous media in the space is simulated, and the three-dimensional surface is reconstructed.)
