Hi there,
hope this gets through to you guys, now with all the spam and whatnot.
Anywho, maybe this has come up before, here is some code
aa = randomu(12L, 200, 100)
ff = findgen(100)
maxs = max(aa, maxind, dimension=2)
print, maxind[0:10]
help, ff[maxind[0:10]]
plot, ff[maxind[0:10]]
Now I find this weird, because maxind is an array of longs clearly
bigger than the size of ff but IDL does not complain and plots
something (btw not what I want but this is solved with array_indices).
Is this something to do with the fact that maxind is a 1D
representation of 2D array indices? I hope it is because otherwise why
does IDL not fall over complaining that maxind[0], which on my machine
is 19200, is bigger than the size of ff.
Mhmm
print, ff[maxind[0]]
falls over
print, ff[maxind[0:1]]
doesn't.
btw print, !version
