Hi Paolo,
Some answers to your question included the idiom (&.|:). This idiom is
very useful when working with tables (matrices). Why? Because, given the
design of J, often operations in terms of rows, as opposed to columns, are
easier to write and (&.|:) allows to port quickly a solution for r

From a discussion a while ago I kept the following:
NB. insert new items into an array - behaves like amend.
ins =: 1 : (':&#x
Following up on Raul's "use transpose" idea:
tbl
0 1 2
3 4 5
6 7 8
insertcol =: 1 : '({. , m , }.)&.|:'
2 (0 0 0 insertcol) tbl
0 1 0 2
3 4 0 5
6 7 0 8

When this happens it's often worth spending a few minutes looking them
up and trying some simple examples so you can see how they work for
the kind of data you're working with.

The classic "insertion" method for J is to use {. for the part before
the insertion and }. for the part after the insertion.
An example of this might be:
table =: 3 3 $ <"0 i.9
column =: 3 1$ (<,'0')
column ((2{."1]),.[,.2}."1]) table
But it also might be simpler to use transpose:

I should have provided some explanation of the version I offered.
The first part executed - the rightmost part - generalizes the Boolean
expansion vector Henry had hard-coded in his examples:
(0) 2}1$~>:{:$table
> 1 1 0 1
This is handy because it helps generalize the defined verb to work in

Hi Henry
Quite hard for a beginner like me
but the one with complex number looks easier to read and remember

Slightly generalized from Henry's examples - the ugly can be hidden under a
cover:
