This module contains the definition of the psb_z_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_z_base_sparse_mat class ! inside another class which is the one visible to the user.
