A straightforward solution would be:
insert =: 1 : (':'; 'x (m&+ each { (<@:i.)"0 $x) } y')
a =: 6 8$0
b =: 4 3$1
b 2 1 insert a
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 1 1 1 0 0 0 0
0 1 1 1 0 0 0 0
0 1 1 1 0 0 0 0
0 1 1 1 0 0 0 0
(but monadic { is maybe not straightforward)

Subject: [Jprogramming] Insert a 2 dimensional array to a n dimensional array
Hello,
I have a question similar to the question I had a few weeks before. The
question was how replace single values from a matrix
(http://jsoftware.com/pipermail/programming/2014-September/039225.html).
Now I would like to replace a matrix with at least 2 dimensions with
values from a 2 dimensional array.
The new values should replace the old values from the matrix, like this:
new data:
1 1 1
1 1 1
1 1 1
old data:
0 0 0 0
0 0 0 0
0 0 0 0
0 0 0 0
result:
1 1 1 0
1 1 1 0
1 1 1 0
0 0 0 0
The insert position to the matrix should be parameterisable.
Best regards
Sebastian
