You can use the VOXELISE function to convert your mesh to a voxelgrid. Use a resolution that makes the most sense to you: too few will decrease your accuracy, too many will cause memory issues. I would suggest picking z-values that do not occur in your mesh, but that is optional.
Then you will have a 3D logical array. You can use findND to get the coordinates of all your voxels: [x,y,z]=findND(L);
The last step is to find the mean values of x,y,z.
