(I accidentally sent this to j.general, to which I'm not yet subscribed; I don't expect that to go through, but if it does, apologies for the duplication.)
Here's a simple question from a rank beginner: Expressing polynomials as, for example, +/1 _1 1*x^i.3 works well, as long as x is a scalar. If x is of higher rank, this stops working. My somewhat brute-force solution is to manually set the rank used, as in: x=:2 3 5 +/1 _1 1*x^_ 0 i. 3 Is this good style? Is there a better way?
