* $Log: ope_helmholtz_minus.C,v $
* Revision 1.8 2014/10/13 08:53:32 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.7 2014/10/06 15:13:15 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.6 2008/07/10 10:59:17 p_grandclement
* forgot another ones
*
* Revision 1.5 2004/08/24 09:14:45 p_grandclement
* Addition of some new operators, like Poisson in 2d... It now requieres the
* GSL library to work.
*
* Also, the way a variable change is stored by a Param_elliptic is changed and
* no longer uses Change_var but rather 2 Scalars. The codes using that feature
* will requiere some modification. (It should concern only the ones about monopoles)
*
* Revision 1.4 2004/01/15 09:15:38 p_grandclement
* Modification and addition of the Helmholtz operators
*
* Revision 1.3 2003/12/11 16:12:10 e_gourgoulhon
* Changed sqrt(2) to sqrt(double(2)).
*
* Revision 1.2 2003/12/11 15:57:27 p_grandclement
* include stdlib.h encore ...
*
* Revision 1.1 2003/12/11 14:48:50 p_grandclement
* Addition of ALL (and that is a lot !) the files needed for the general elliptic solver ... UNDER DEVELOPEMENT...
