MATLAB: Problem with fsurf (where is the controur?)

fsurfMATLAB

using:

f = @(x,y) (x^0.3)*(y^0.3)
fsurf(f,[0,10],'ShowContours','on')

but I do not seem to get the countour below the surface, only the surface. Why?

When I try in R2019a, the contour is there, but you need to rotate the plot to see it as it is underneath the surface.

Thank you very much. I summarize your idea in this code:

% 
ax = axes('XLim',[-1.5 1.5],'YLim',[-1.5 1.5],'ZLim',[-1.5 1.5]);
view(2)
f = @(x,y) x;
g = @(x,y) y;
h = @(x,y) x*0;
hfsurf = fsurf(f,g,h);
t = hgtransform('Parent',ax);
set(hfsurf,'Parent',t);
Rz = makehgtform('xrotate',pi/4);
set(t,'Matrix',Rz);
