! package: psb_c_base_mat_mod
!
! This module contains the implementation of the
! psb_c_base_sparse_mat, derived from the psb_base_sparse_mat to
! define a middle level definition of a complex, single-precision sparse
! matrix object.This class object itself does not have any additional
! members with respect to those of the base class. No methods can be
! fully implemented at this level, but we can define the interface for
! the computational methods requiring the knowledge of the underlying
! field, such as the matrix-vector product; this interface is defined,
!
! This module also contains the implementation of the
! psb_c_coo_sparse_mat type and the related methods. This is the
! reference type for all the format transitions, copies and mv unless
! methods are implemented that allow the direct transition from one
! format to another. The psb_c_coo_sparse_mat type extends the
! psb_c_base_sparse_mat one.
!
! About the method MOLD: this has been defined for those compilers
! not yet supporting ALLOCATE( ...MOLD=...); it's otherwise silly to
! duplicate "by hand" what is specified in the language (in this case F2008)
!
