.SH NAME
eye \- identity matrix and preconditionner (rheolef-7\&.2)
.SH "DESCRIPTION"
.PP
Following e\&.g\&. \fCoctave\fP, \fCeye\fP denotes the identity matrix\&. Here, \fC\fBeye()\fP\fP is a function call that returns the identity preconditionner as a \fBsolver(4)\fP\&.
.PP
The dimensions of \fC\fBeye()\fP\fP 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\&. \fBcg(5)\fP for an example\&.
