Incrementing an Array [message #24903]

Once again I am struggling with the finer points of IDL. What I am trying
to do seems simple, but is causing me some headaches. What I am trying to
do is this:

matrix[x,y,z] = matrix[x,y,z] + 1

Where matrix is a 3D array and x,y,z are 1D arrays. Matrix starts out
all 0's and I am trying to increment values at elements [x,y,z]. The
problem
is that some elements should be incremented multiple times. All the
proper elements are incremented once, but the second, third,
fourth....increments are not showing up. Any ideas? I know that I could
write this with loops, but that would be too slow.

Thanks,

Alan
