! package: psb_d_mat_mod
|
|
!
|
|
! This module contains the definition of the psb_d_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_d_base_sparse_mat class
|
|
! inside another class which is the one visible to the user.
|
|
! Most methods of the psb_d_mat_mod simply call the methods of the
|
|
! encapsulated class.
|
|
! The exceptions are mainly cscnv and cp_from/cp_to; these provide
|
|
! the functionalities to have the encapsulated class change its
|
|
! type dynamically, and to extract/input an inner object.
|
|
!
|
|
! A sparse matric has a state corresponding to its progression
|
|
! through the application life.
|
|
! In particular, computational methods can only be invoked when
|
|
! the matrix is in the ASSEMBLED state, whereas the other states are
|
|
! dedicated to operations on the internal matrix data.
|
|
! A sparse matrix can move between states according to the
|
|
! following state transition table. Associated with these states are
|
|
! the possible dynamic types of the inner matrix object.
|
|
! Only COO matrices can ever be in the BUILD state, whereas
|
|
! the ASSEMBLED and UPDATE state can be entered by any class.
