Will the new array always be larger, always be smaller, or be larger or
smaller at different times during the run?

If the new array is always smaller, a relatively simple folding can be
done.  Depending on the meaning of your arrays, you may need to split
entries and fold part of the value down and part of the value up.

If the new array is always larger, you're going to have to determine how to
split the value in one entry into two or more entries.

What do the values in these arrays represent?  I am only familiar with
resampling in the context of audio waveforms and video images / pixel maps.
 Neither of those cases requires the sum of the entries to be the same
after resampling as before, so I am curious what you are trying to resample.
