not in the core pd.

but there are libraries like Gem, providing [v+] [v*] (for 
adding/multiplication vectors and scalars), zexy [.] (in product of 
either 2 vectors or 1 vector and 1 scalar; note: zexy also provides a 
[tabset] so you might get a name-clash)

furthermore there should be johannes taelman's SMlib, which provides a 
lot of objects for dealing with vectors (and very complex operations too)

if you don't want to use any other lib, you could copy the content of 
one table to another table (with [tabread] & [tabwrite] and doing the 
math on scalars)
