Always a pleasant surprise to find niche or mundane uses of array languages. I really appreciate the explication because it made it possible for me to follow along in J - there's vanishingly little material to patiently explain bits like the "grade-up grade-down to return rank" that permeates so much APL-style code. I'm similarly pleased to have found a correspondence from K's ' (also present in Klong) to J, where it ends up being "0 in this instance. r=. v&%"0 (0.5+i. s)
+/s>($r)$/:\:,/r
