f(x,y)= (-1/a^2)*(x*y)^(1/a-1)+(1/a)*x^(1/a-1)+(1/a)*y^(1/a-1) =0

x,y here are interdependent. From my point of view,

`firstly, you can try to solve it symbolically. If no closed form found,
``then you can specify some values of y/x and thus solve x/y numerically
``using fzero
`
To plot the figure, it is straightforward.
x=linspace(.1,1);y=linspace(.1,1);
[xx,yy]=meshgrid(x,y);
fxy=f(xx,yy);
mesh(xx,yy,fxy);
