/*Class:eye
NAME: @code{eye} - the identity matrix
DESCRIPTION:
Following matlab, the name @code{eye()} is used in place of I to denote identity matrices
because I is often used as a subscript or as sqrt(-1). The dimensions of @code{eye()} are
determined by context.
The preconditioner interface is usefull when calling algorithms without any
preconditioners, e.g.
@example
int status = pcg (a, x, b, eye(), 100, 1e-7);
@end example
