</div>because the important output is the new unit cell,<br>
described by the primitive vectors. Vectors are written<br>
in units of celldm(1) only in order to produce an output<br>
format that looks like the input one. One may always<br>
redefine celldm(1) in such a way that it is the length<br>
of one of the primitive vectors ( a typical definition of<br>
lattice parameters "a")<br>
