_function.SymLat

Name:
_function.SymLat

Definition:

   
    The function
              v  =  SymLat( s )

    returns a vector of the cell translations applied to the coordinates
    from the character string of the form 'n_pqr'. i.e. p-5, q-5, r-5.

Type: Integer

Values appear in Matrix context.

Dimension: [3]

Units: none

Evaluation method:

    Function SymLat( s :[Single, Symop])  {  # symop string

           If (s[0] == ' ')  v = [ 5, 5, 5 ]
           Else              v = [ AtoI(s[2]), AtoI(s[3]), AtoI(s[4]) ]

                 SymLat  =  v - 5
    }
