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.

surface plots are not compatible with gaps.
You can draw a surface plot and contour3() on top of it. That would require that you create a grid of function values to contour3()
You could fsurf() and set the Alpha (transparency) of it fairly low so that you could see the contour lines underneath.
f = @(x,y) (x.^0.3).*(y.^0.3);
[X,Y] = meshgrid(linspace(0,10));
Z = f(X,Y);
surf(X, Y, Z, 'edgecolor', 'none')
alpha 0.5
hold on
contour(X, Y, Z);
hold off
