Ran in:
As you have a single values, you may plot only a single point.
x=5.3;
z= 7.8 ;
iwant = x*z/(x/z)^2+14*x^2-0.8*z^2
iwant = 434.1261
But if you have a vector, you can plot:
x=linspace(2,5.3);
z= linspace(5,7.8) ;
[x,z] = meshgrid(x,z) ;
iwant = x.*z./(x./z).^2+14*x.^2-0.8*z.^2 ;
surf(x,z,iwant)
