Follow-up Comment #1, bug #47707 (project octave):
The script doesn't say what issues it is trying to avoid. Do you know what
they are? I'd have thought that working with integers would be the way to
go.
Alternatively, do you need a histogram of your whole 4-D image, or is a
histogram over one or two dimensions? A compromise may be to convert only one
row/column/page/... at a time to double.
However, I thought that "hist" was being phased out by Matlab in favour of
"histogram". (I haven't checked the differences.) Perhaps we should just
write an efficient implementation of that and leave hist.
