Aa! donc vos x et y sont quand même bien rangés ! Ce qui permet d'utiliser:

X = [
   -38.873948  -38.779007  -38.684192  -38.589505  -38.494945

   -34.795279  -34.703043  -34.610931  -34.518942  -34.427076
   ];
Y = [
   -38.348145  -37.045021  -35.743643  -34.444008  -33.146112
   -38.351151  -37.047922  -35.746441  -34.446702  -33.148702
   -38.354156  -37.050824  -35.749239  -34.449396  -33.151293

   -38.360169  -37.056629  -35.754836  -34.454786  -33.156477
   ];
M = [
     361.36567    363.89887    362.30396    361.63436 363.50173
     355.32577    352.35042    355.32577    355.18551 354.76388

     344.9951     346.04946    344.84378    346.1994 348.28099
    ];

surf(X,Y,M);
ax = gca();
ax.view = "2d";
// pour modifier la colormap, je vous laisse faire.
