WebWhen lattice parameters of unit cell (set by POSCAR) are the column vectors of a u, b u, and c u, those of supercell, a p, b p , c p, are determined by, ( a p b p c p) = ( a u b u c u) M _ p. M p is a change of basis matrix and so M p − 1 must be an integer matrix. http://phonopy.github.io/phonopy/symmetry.html
