* Revision 1.4 2014/10/13 08:53:26 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.3 2014/10/06 15:16:06 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.2 2008/08/19 06:42:00 j_novak
* Minor modifications to avoid warnings with gcc 4.3. Most of them concern
* cast-type operations, and constant strings that must be defined as const char*
*
* Revision 1.1 2007/12/11 15:42:23 jl_cornou
* Premiere version des fonctions liees aux polynomes de Jacobi(0,2)
*
* Revision 1.2 2004/11/23 15:16:01 m_forot
*
* Added the bases for the cases without any equatorial symmetry
* (T_COSSIN_C, T_COSSIN_S, T_LEG, R_CHEBPI_P, R_CHEBPI_I).
*
* Revision 1.1.1.1 2001/11/20 15:19:29 e_gourgoulhon

* Initialisation a zero du tableau xo avant le calcul.
*
* Revision 2.3 1999/11/15 16:39:17 eric
* Tbl::dim est desormais un Dim_tbl et non plus un Dim_tbl*.
*
* Revision 2.2 1999/10/18 13:40:11 eric
* Suppression de la routine _sx_r_chebu car doublon avec _sxm1_cheb.
