Suppose i have
a: 0 0 1 0 0 2 0 0 0
and I would like to forward fill the zeros to get
filled: 0 0 1 1 1 2 2 2 2
I tried using amend at @[]
a: @[a;where a=0;0N];
fills a
but i get the error:
'type
[0] a: @[a;where a=0;0N]
I've also tried replacing 0N with null and :: in the amend at statement but none of these approaches work. What do I do?
The issue is that you need to amend a as follows:
a:@[a;where a=0;:;0N]
Then you can get your expected output with:
0^fills a
