! package: psb_s_base_vect_mod

! This module contains the definition of the psb_s_base_vect type which
! is a container for dense vectors.
! This is encapsulated instead of being just a simple array to allow for
! more complicated situations, such as GPU programming, where the memory
! area we are interested in is not easily accessible from the host/Fortran
! side. It is also meant to be encapsulated in an outer type, to allow
! runtime switching as per the STATE design pattern, similar to the
! sparse matrix types.

! package: psb_z_base_vect_mod
!
! This module contains the definition of the psb_z_base_vect type which
! is a container for dense vectors.
! This is encapsulated instead of being just a simple array to allow for
! more complicated situations, such as GPU programming, where the memory
! area we are interested in is not easily accessible from the host/Fortran
! side. It is also meant to be encapsulated in an outer type, to allow
! runtime switching as per the STATE design pattern, similar to the
! sparse matrix types.
