|
|
!! The psb_d_base_sparse_mat type, extending psb_base_sparse_mat,
|
|
!! defines a middle level real(psb_dpk_) 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.
|
|
!!
|
|
!! 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)
