structures? [message #85772]

Hi,

I'm trying to avoid cumbersome loops, and think that using structure
arrays or pointers, along with index handling, should help. Say we want
to build a table of data for each day in a sequence of julian days. The
rows in the table for each day represent a unique time of that day. Now
we want to examine a collection of files containing data for a
particular date/time, and assign each row to the corresponding row in
the table for that day. I envision doing this as follows:

n_days=10
a_arr=replicate({idxvar:0.0, table:fltarr(10, 10)}, n_days)

where idxvar represents a julian day, and the table contains the time
series for that day. We could then loop through each file, examining
each row and determining which day and which table row in a_arr the row
belongs to. Is there a better way to approach this? My concern is that
the tables for each day could be very large if the time step in the
time series is very small (say a second), and also there could be a
large number of days to build time series for. Is this one of those
cases where looping, while horrible, is a more resource-friendly way to
deal with this?

Thanks,
