NAME

       eye - identity matrix and preconditionner (rheolef-7.2)

DESCRIPTION

       Following e.g. octave, eye denotes the identity matrix. Here, eye() is a function call that returns the
       identity preconditionner as a solver(4).

       The dimensions of eye() are determined by the context. This class is useful in the context of
       preconditionner interfaces: it allows one to specify a do-nothing preconditionner. See e.g. cg(5) for an
       example.
