[(2 _2) +&.> (6&*)&.> 1 2; 1 2 3] worked .. but i wanted to combined
it into one expression.
- for me at the moment, getting an understanding of J is more important
than a bare result. (And i didn't like the exra box op.)
another prob i'm having, which ought to be simple is:
creating a concatenated list from boxed lists:
i.e.
Jmagic 1 2;3 4 5
NB. -> 1 2 3 4 5
i can do :
a,b [ 'a b' =. 1 2; 1 2 3
NB. -> 1 2 3 4 5
but i feel i ought to be able to do this as some sort of variant of
f&:> 1 2; 1 2 3
where [f] involves some [,] activity.
.. My water tells me this should be a simple expression. But i cant seem
to apply a [,] before a filler [0] is added to the short list.
