This module contains the definition of the psb_s_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_s_base_sparse_mat class ! inside another class which is the one visible to the user. ! Most methods of the psb_s_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. ! !
