Variable density of 3d objects in matlab??

Is it possible to assign variable density or different densities to different portions of the object. I plan to perform FEA on such object.

Yes. If you have a volumetric image - a 3D image with a value for every single (x,y,z) coordinate - then the density could simply be the value of the array at that location.
