A design of measurement matrices of satisfying the incoherence criterion or Restricted Isometry Rroperty is among the core issues of compressed sensing theory. Whether there is an optimal determinate measurement matrix for some stable reconfiguration algorithms is one of the key problems which need to be solved urgently in compressed sensing. For the fixed(More)
The classification of filter is discussed by analysis the relationship between the filter and the intersection of all members. It is obtained that on the infinite set there exists three types of filter, which are free, principal and preprincipal filter. It is proved that the sufficient and necessary condition of u is a free ultra filter by the properties of(More)
