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\&. .SH "IMPLEMENTATION" .PP This documentation has been generated from file linalg/lib/eye\&.h .SH AUTHOR Pierre Saramito .SH COPYRIGHT Copyright (C) 2000-2018 Pierre Saramito GPLv3+: GNU GPL version 3 or later .
