= Test de la fonction objective =

== Configuration pour le test ==
 * TA=10,NX=32,NY=22,NZ=31
 * paramètre de contrôle: 1 seul (parmi sshn_c, ta_c, sa_c, ua_c et va_c)
 * obs : 3D a Yt=10 : sshb, tb, ub, vb (forward de GYRE_0000300_restart.nc)
 * init : GYRE_0000400_restart.nc

== Paramétrage ==
Objective Function TEST : with: 
pdx = 1.000000e+00, (a)lpha = 5.000000e-02
fdec= 2.000000e+00, (n)bloop= 10

 * dx = Xo * pdx 
 * a(n) = a(n-1) / fdec 
 * g = (J(Xo+a.dx) - J(Xo)) / (@J/@Xo).a.dx
        

== Résultats ==

 * paramètre de contrôle: ua_c
