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);
