Re: [Jprogramming] Rank difficulties

I think it would need specifying rank 0 and using /. m=: i. 5 4 3 0 2 {"0 2/ m NB. slices 0 2 at rank 2 0 1 2 12 13 14 24 25 26 36 37 38 48 49 50 6 7 8 18 19 20 30 31 32 42 43 44 54 55 56 slice =: {{ {"(0,m)/ }} NB. the same $0 2(3 slice) m 2 5 3 This way, the number of slices i
