[Octave-bug-tracker] [bug #63376] tsearchn quite slow (compared to tsearch)

[Rik]

Follow-up Comment #1, bug #63376 (project octave):

Using the profiler, it looks like it is not just the for loop.  The conversion
of Cartesian to barycentric coordinates (a subfunction in tsearchn.m) is what
is taking most of the time.
