Follow-up Comment #4, bug #45877 (project octave):
Thanks, Rik,
Is the mahal.m that I sent satisfactory? Is there anything else I need to
do?
Out of interest, what was the rationale for deprecating mahalanobis? As I
pointed out, it is a *different* function from mahal.
Since it isn't a common function, and isn't in Matlab, it is likely that
nobody was using it, but I don't understand the motivation for removing it.
If there was an existing log10 but not log, would you remove log10 when log
was implemented? This is much worse than that, because log10 can easily be
calculated from log, but mahalanobis can't (as?) easily be calculated from
mahal.
