! package: psb_s_csr_mat_mod
|
|
!
|
|
! This module contains the definition of the psb_s_csr_sparse_mat type
|
|
! which implements an actual storage format (the CSR in this case) for
|
|
! a sparse matrix as well as the related methods (those who are
|
|
! specific to the type and could not be defined higher in the
|
|
! hierarchy). We are at the bottom level of the inheritance chain.
|
|
!
|
|
! Please refere to psb_s_base_mat_mod for a detailed description
|
|
! of the various methods, and to psb_s_csr_impl for implementation details.
