I'm unfamiliar with the use of structures, but I'm guessing this is the
answer. Lets say I have some program generate arrays using the following
algorithm:
For I=1,5 do begin
temparr=fltarr(i)
Endfor
I want to "collect" all of the temparr that are created within the loop such
that I can access each array by some sort of index (which would be from 0 to
4) -- e.g. I want to be able to do something like:
A = temparr at index 2
Print,A
--> (0,1)
An obvious solution is to put "0s" in and make a 2d array, where the row is
the index, so I get something like
0,0,0,0,0
0,1,0,0,0
0,1,2,0,0
0,1,2,3,0
0,1,2,3,4
However, this takes up a lot of space and the nature of the algorithm I want
to use I would like to have smaller arrays be "compressed" without having to
crop them each time.
What do I put inside the for loop to generate:
1:0
2:0,1
3:0,1,2
4:0,1,2,3
5:0,1,2,3,4
???
Thanks!
