<p>So let’s say I have the G-code file for 3D printing a cube, and I have a density function F(x,y,z). How would I change, in G-code, the density at each specific point in the cube, so it has the general distribution of the function?</p>

Could you please explain how a change in density relates to 3D printing?

I apologize. I meant, if I wanted to 3D print, in GCode, a cube of a specified length which has a density distribution described some function F(x,,y,z)

Why do you want to do that? And what is the density? Is this related to the infill or the actual density? A G-code is sliced geometry containing the information of the selected options during slicing, if you change the extrusion modifier, your geometry will also change if applied to the walls.

@0scar, I mean the actual density. I want the density of the cube to vary according to the function. I just thought it would be a fun project. Are you saying that if I change the density at the walls, I will have to change the shape of the cube?

If you change the extrusion modifier, the lines get wider, so you need to apply this to the infill only, otherwise you'll get a distorted print object.
