_function.SymEquiv

Definition:

   
    The function
                xyz' =  SymEquiv( symop, xyz )

    returns a fractional coordinate vector xyz' which is input vector
    xyz transformed by the input symop 'n_pqr' applied to the
    symmetry-equivalent matrix extracted from the category SPACE_GROUP_SYMOP.

Type: Real

Values appear in Matrix context.

Dimension: [3]

Units: none

Evaluation method:

    Function SymEquiv( c :[Single, Symop],    # symop string n_pqr
                       x :[Matrix, Real]   ){  # fract coordinate vector

            s = space_group_symop [ SymKey( c ) ]
            SymEquiv = s.R * x + s.T + SymLat( c )
    }
