Summing arrays without loops [message #27317] Tue, 16 October 2001 14:07

Hello IDL users,

I have a 3d array of daily precipitation data for the globe that I would
like to sum for the entire year but I would like to do it without looping.
The array is initialized as follows:

IDL> data = fltarr(365,192,94)

where 365 is the number of days, 192 is the number of longitudes and 94 is
the number of latitudes.

Is there a way to sum the daily values without writing a nested loop?

Thanks in advance for your input.
