This module contains the implementation of the ! psb_s_base_sparse_mat, derived from the psb_base_sparse_mat to ! define a middle level definition of a real, 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, ! but is supposed to be overridden at the leaf level. ! ! This module also contains the implementation of the ! psb_s_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_s_coo_sparse_mat type extends the ! psb_s_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) ! module psb_s_base_mat_mod use psb_base_mat_mod use psb_s_base_vect_mod type, extends(psb_base_sparse_mat) :: psb_s_base_sparse_mat contains procedure, pass(a) :: s_sp_mv =>
