Hi,
As far as I know, unless toggled by some switch, as mentioned by
J. Koski for the present case, the function is chosen according
to the place of its directory in the path variable. My policy
in such cases is to copy the preferred version under another name
to a directory where I keep my own m files. I have to change the
name of the function in its definition, as well.

The function addpath with the option -begin may provide a better
way: Create a special directory for such cases, put it at the
head of the path list with addpath (it is best to do it in the
.octaverc file) and copy to there the preferred versions of the
functions. In this case you don't have to change the name of the
function, nor to alter its text.

The idea just occured to me. I never tried it.
Cheers, Avraham
