! package: psb_base_mat_mod
|
|
!
|
|
! This module contains the definition of the very basic object
|
|
! psb_base_sparse_mat holding some information common to all matrix
|
|
! type variants, such as number of rows and columns, whether the
|
|
! matrix is supposed to be triangular (upper or lower) and with a unit
|
|
! (i.e. assumed) diagonal, together with some state variables. This
|
|
! base class is in common among all variants of real/complex,
|
|
! short/long precision; as such, it only contains information that is
|
|
! inherently integer in nature.
|
|
!
|
|
! The methods associated to this class can be grouped into three sets:
|
|
! 1) Fully implemented methods: some methods such as get_nrows or
|
|
! set_nrows can be fully implemented at this level.
|
|
! 2) Partially implemented methods: Some methods have an
|
|
! implementation that is split between this level and the leaf
|
|
! level. For example, the matrix transposition can be partially
|
|
! done at this level (swapping of the rows and columns dimensions)
|
|
! but it has to be completed by a method defined at the leaf level
|
|
! (for actually transposing the row and column indices).
|
|
! 3) Other methods: There are a number of methods that are defined
|
|
! (i.e their interface is defined) but not implemented at this
|
|
! level. This methods will be overwritten at the leaf level with
|
|
! an actual implementation. If it is not the case, the method
|
|
! defined at this level will raise an error. These methods are
|
|
! defined in the serial/f03/psb_base_mat_impl.f03 file

|
|
!! The basic data about your matrix.
|
|
!! This class is extended twice, to provide the various
|
|
!! data variations S/D/C/Z and to implement the actual
|
|
!! storage formats. The grandchild classes are then
|
|
!! encapsulated to implement the STATE design pattern.
|
|
!! We have an ambiguity in that the inner class has a
|
|
!! "state" variable; we hope the context will make it clear.
|
|
!!
|
|
!!
|
|
!! The methods associated to this class can be grouped into three sets:
|
|
!! - Fully implemented methods: some methods such as get_nrows or
|
|
!! set_nrows can be fully implemented at this level.
|
