To convert from three index notation to four index notation for a hexagonal lattice.
Language: | FORTRAN |
Product form: | Source code |
MAP_CRYSTAL_NOTAT2 converts from three index notation to four index notation for the hexagonal lattice system. If the components in three index notation are U,V,W, then the components in four index notation are given by:-
U1 = (2U - V)/3, U2 = (2V - U)/3, U3 = W, U4 = -(U + V)/3 in real space, or
U1 = U, U2 = V, U3 = W, U4 = -(U + V) in reciprocal space.
