Hello,
is it possible to turn of the grid of a surface plot, but keep the edge on?
If I do this, I have no grid and no edge:
Z1 = (0.5 .*(a1.*exp(-b1.*X1)+ e1.*exp(-f1.*X1))-c1.*exp(-d1.*X1)).*Y1.^2 +0.5.*(a1.*exp(-b1.*X1)-e1.*exp(-f1.*X1)).*Y1+c1.*exp(-d1.*X1)
s = surf(X1,Y1,Z1,'FaceColor',[0.1 0.0 1.0],'FaceAlpha',0.8,'EdgeColor', 'black','LineStyle','none', 'EdgeAlpha',0.2,'FaceLighting','flat')
hold on;
If I do this, I have a grid and an edge line:
Z1 = (0.5 .*(a1.*exp(-b1.*X1)+ e1.*exp(-f1.*X1))-c1.*exp(-d1.*X1)).*Y1.^2 +0.5.*(a1.*exp(-b1.*X1)-e1.*exp(-f1.*X1)).*Y1+c1.*exp(-d1.*X1)
s = surf(X1,Y1,Z1,'FaceColor',[0.1 0.0 1.0],'FaceAlpha',0.8,'EdgeColor', 'black','LineStyle','-', 'EdgeAlpha',0.2,'FaceLighting','flat')
hold on;
Thank you:)

[X,Y] = meshgrid(1:10) ;
Z = sqrt(X.^2+Y.^2) ;
% plot the outer line
X1 = X ; X1(2:end-1,2:end-1) = NaN ;
Y1 = Y ; Y1(2:end-1,2:end-1) = NaN ;
Z1 = Z ; Z1(2:end-1,2:end-1) = NaN ;
surf(X,Y,Z)
shading interp
hold on
plot3(X1,Y1,Z1,'k*')

Just serve yourself with plot3 commands
[X,Y,Z] = peaks;
surf(X,Y,Z,'edgecolor','none');
hold on
plot3(X(1,:),Y(1,:),Z(1,:),'k','LineWidth',2)
plot3(X(end,:),Y(end,:),Z(end,:),'k','LineWidth',2)
plot3(X(:,1),Y(:,1),Z(:,1),'k','LineWidth',2)
plot3(X(:,end),Y(:,end),Z(:,end),'k','LineWidth',2)
