Humm. A memory problem? I don't know. 1.4 million
array elements seems like a lot, but I can
easily do this:
IDL> a=FltArr(3660, 1680)
IDL> b = randomu(seed, 1407735L) * 3600L * 1680L
IDL> a[b] = 5
I have a problem, however, when I add a third
dimension:
IDL> DelVar, a
IDL> a = FltArr(3660, 1680, 8)
IDL> a[b,b, *] = 5
% Array has too many elements.
IDL> a[b,b, 0] = 5
% Array has too many elements.
I don't know what that is. I think you are going to have
to ask RSI.
I do notice that if I do this:
IDL> c= b[0:4999]
IDL> a[c,c,*] = 5
That my computer gets very, VERY unhappy. :-(
I had to reboot to get some response back.
I think this means there is something going on here
that I don't understand. :-)
Cheers,
David
