[Jprogramming] stitching matrices

What Brian is pointing out is that for the use case you're studying, both the definitions you quoted are irrelevant.

Because your use of & appears in the left tine of a hook, it will be invoked dyadically.  That is, with two arguments: x and y . You need to look for definitions of & which involve x and y .

But take heed of Raul's warning.  Even when you've identified the applicable definition and valence of & , there's still rank to consider before you can make any substitutions.

In short: you can't apply these identities (or any other in the dictionary) blindly.  Context is important.
