⎕dfn ⎕Create a dyadic tabling function from the dyad dfn.
If the resulting function is passed vectors of length m and n, the result of f will be an m×n 'matrix' (a list of m items, each of which is a list of n items) such that a⌷b⌷(x f⎕ y) is (b⌷x) f (a⌷y).
For example:
("A: " "B: ")+⎕("One" "Two")
((A: One A: Two ) (B: One B: Two ) )
(1 2 3)×⎕(5 7 11)
((5 7 11 ) (10 14 22 ) (15 21 33 ) )
The ContextException is thrown if dfn is not dyadic.
