Hi Real beginner here
a =: 1 2 3 4 |. a 4 3 2 1 NB. yep, all is well now: a=: 2 3 $ i.6 a 0 1 2 3 4 5 1 |. a 3 4 5 0 1 2 NB. wow! looks like "rotate up", to me (intermission while I find out about rank,axis and frame!) oh ok 1 0 |. a 3 4 5 0 1 2 NB. hmm rotate 1 on the elements of first axis - so rotate the 1 cells that form the rows and no rotation on the elements of the second axis 0 1|. a 1 2 0 4 5 3 NB. ok - rotate 1 on elements of the second axis - so rotate the 0 cell elements of the 1 cells that form the rows 1 |. "1 a 1 2 0 4 5 3 NB - yep I guess my question is about the name "rotate left" - that's only the "visual result" if the right operand is a 1 cell - why not call it "rotate"? another possibility is that I still don't understand rank/axis/frame!!! :) cheers -- A/Prof Chris Wright MBBS, FRACP, FCICM, GradDipiSc(Physics) Academic Coordinator, Years III - V Central MBBS Intensive Care Specialist Faculty of Medicine, Nursing and Health Sciences, Monash University Clayton VIC ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
