How can I specify the voxel size for converting a stl file into a volume?

I am using the function: mesh voxelization https://es.mathworks.com/matlabcentral/fileexchange/27390-mesh-voxelisation, but I don't see how I can specify the voxel size, I can specify the dimensions as input but I don't know which voxel size it is using. Polygon2voxel https://es.mathworks.com/matlabcentral/fileexchange/24086-polygon2voxel is also an option but I don't know how to specify the voxel size neither. Any suggestion is really welcomed. Thank you.

It's in the functions description: function Volume=polygon2voxel(FV,VolumeSize,mode,Yxz)

Therefore: vol = polygon2voxel(FV,[120, 120, 120],...);

Correct. Both tools are documented and include usage examples.

Here is one additional example of using #27390. The voxel size is either explicitly defined by the grid pitch, or it's implicitly specified as a fraction of the bounding box size.
