_function.Symop
Name:_function.Symop
Definition:
The function
s = Symop( n, t )
returns a character string of the form 'n_pqr' where n is the
symmetry equivalent site number and [p,q,r] is the cell translation
vector plus [5,5,5].
Type: Symop
Evaluation method:
Function Symop( n :[Single, Integer], # symmetry equivalent site number
t :[List , Integer]) { # cell translation vector
d = t + 5
Symop = repr(n) + '_' + repr(d[0]) + repr(d[1]) + repr(d[2])
}
