Hey, I just got to using scatter amend. I cannot figure out in what form it wants x when everything is boxed. It whines about length. My case is:
y is boxed array of shape 3 3 3 3 m is a boxed array of shape 3, ultimately selecting 21 cells, a face, row, and column (if you "9 9$," the y) For x, I've tried:i.21 <"0 i.21 <<"0 i.21 i.21 1 <"0 i. 21 1 I tried with 27 too, in case it does 3 runs of 9 each. MWE: Q=:i.3 9 9 $, (???) ((1;1;Q;Q);(Q;Q;1;1);,(<1;Q;1;Q)) } <"0 i.4#3 Non-scalar value don't work. What am I doing wrong? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
