! package: psb_d_scsr_mat_mod
!
! This module contains the definition of the psb_d_scsr_sparse_mat type
! which is just an example of how to build a new storage format.
! Indeed this is simply CSR under a new name.
!
! Please refere to psb_d_base_mat_mod for a detailed description
! of the various methods, and to psb_d_scsr_impl for implementation details.
