To rotate a matrix by its axes separately one does (=i.2)|.i.3 4 4 5 6 7 8 9 10 11 0 1 2 3
1 2 3 0 5 6 7 4 9 10 11 8 This works as expected. However (=i.2)|."2 i.3 4 5 |length error | (=i.2) |."2 i.3 4 5 This is strange, since it should be equal to (=i.2)|.&>&<"2 i.3 4 5 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 0 1 2 3 4 1 2 3 4 0 6 7 8 9 5 11 12 13 14 10 16 17 18 19 15 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 20 21 22 23 24 21 22 23 24 20 26 27 28 29 25 31 32 33 34 30 36 37 38 39 35 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 40 41 42 43 44 41 42 43 44 40 46 47 48 49 45 51 52 53 54 50 56 57 58 59 55 What's wrong?
