P.S. if you want to avoid boxing (for speed):
($old)$(,new) (($old) #. ($new) #: i.$,new)} ,old
1 1 1 0
1 1 1 0
1 1 1 0
0 0 0 0
($old)$(,new) (($old) #. 0 1+"1 ($new) #: i.$,new)} ,old
0 1 1 1
0 1 1 1
0 1 1 1
0 0 0 0
Thanks,

You can replace the 0 1 with any valid coordinate for the upper left corner.
You can either make this an explicit definition, or
14 15
(0 0 toV 2 2) (1 advswap '}') i.4 4
1 1 1 3
1 1 1 7
1 1 1 11
12 13 14 15

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 dim
