! package: psb_c_mat_mod
!
! This module contains the definition of the psb_c_sparse type which
! is a generic container for a sparse matrix and it is mostly meant to
! provide a mean of switching, at run-time, among different formats,
! potentially unknown at the library compile-time by adding a layer of
! indirection. This type encapsulates the psb_c_base_sparse_mat class
! inside another class which is the one visible to the user. All the
! methods of the psb_c_mat_mod simply call the methods of the
! encapsulated class.
