Oh, yes... you are correct. It's pretty easy to see that the listed definition does not match the implementation. Here's an implementation that matches the dyadic definition: dytay=: (1 :0) ("0) : (x^y) * u t. y ) 0 1 2 ^dytay/ 0 1 2 1 0 0 1 1 0.5 1 2 2 0 1 2 ^t./ 0 1 2 1 1 1 _ 1 0.5 _ _ 1 That said, I am not seeing why this definition is useful. Am I missing an important concept? -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
