I missed this requirement.

for different values of "a"

x=linspace(.1,1,20);y=linspace(.1,1,20);[xx,yy]=meshgrid(x,y);
for a=[1.1,1.2,1.5,2]
Hfxy=@(x,y)(
(-1/a^2)*(x.*y).^(1/a-1)+(1/a)*x.^(1/a-1)+(1/a)*y.^(1/a-1));
Dfxy=Hfxy(xx,yy);
figure;surf(xx,yy,Dfxy);shading interp;fflush(1);
end

`BTW: when I firstly divided both x,y into 100 grid points, GNU plot
``functions very very slow(Octave 3.2.0, GNU plot 4.3.0). I much appreciate
``you help if someone can tell me how to improve its performance.
