The interpreter is working as specified. The result is not "intuitive"
because in this case
atoms of the index array do not select subarrays that are the same
shape. -- RogerHui 2006-07-18 23:06:08
Where exactly this is specified? Dictionary page for } does not mention
shape of subarrays.
Could somebody please explain me where asterisk in top left corner is
coming
from?
'*' ((<1;2 3),<0;7) } 2 9$'-'
