[Octave-bug-tracker] [bug #54241] Lookup documentation

[Dan Sebald]

Follow-up Comment #8, bug #54241 (project octave):

Here's one case where lookup is used with non-increasing table:


@linux ~/octave/octave/octave $ grep "lookup" */*/*.m
[snip]
scripts/statistics/discrete_inv.m:  inv(k) = v(length (p) - lookup (sort (p,
"descend"), x(k)) + 1);
[snip]


I would say, looking at all the uses of lookup, there is a lot of table
truncating and post-call "+1" going on.  So, one wonders if either the calls
to lookup() could make use of the "lr" option, or maybe the location that is
calling lookup() could use find() or ismember() creatively to achieve the same
effect.
