I'm not perfectly sure what "single-valued
mapping" intended but it probably should mean
that for any given input -- which may have any
number of components -- it yiields a unique
output ("value").  So, the domain might be a set
of ordered n-tuples, not just single items.  If
that is what you want, a function from input to
output, then {fancu} is probably your best word. 
Or some compound of it, if there are details tht
need special treatment.
