temp "all"|<name>|<number>,<u11>,<u22>,<u33>
temp "all"|<name>|<number>,<u11>,<u22>,<u33>,<u12>,<u13>,<u23>
This command sets the anisotropic temperature factor U(ij) for
"all" or the atoms specified either by <name> or atom type
<number>. If just a single further parameter <u11> is given,
an isotropic temperature factor is assumed. Otherwise just
the diagonal or all elements of the tensor can be specified.
Note that U(i,j)=<u(i)u(j)> and specifically for the diagonal
elements U(ii)=<u(i)**2> !
