The function is in the package now. This bug can be closed.

Thanks for your reports.
no the packages ar enot identiacal. Indeed geometry defines itself as a fork of matgeom, although we ar ein tight communication with David, we are slowly diverging.

However, your problem comes fomr the workflow I was following in the past. I ported th efunctions ot octave, meaning that befor eincluding them in geomtry I would write a texinfo documentation. This was making the process to slow, so since geomtry 3.0 I just test that the function works in octave stable, I might write soem test and dmeos and then I add it to the package.
So it is expected that your problmes will be soon solved. If you can help to this process you are welcome. Again the steps are:
1. check if the function from MatGeom works in Octave stable release
2. Write at least a demo
3. Write at least a test

2. and 3. are desired but optional.

From time to time I do profile the functions that I use the most and improve them, being in temrs of length of code, or speed. This usually propagates back to matgeom.

one more missing: isPointInPolygon

Maybe I do not understand the relation between octave geometry package and David Leglands geometry library published here:

Shouldn't this be identical?

There seem more functions to be missing compared to the functions listed on https://github.com/dlegland/matGeom/wiki/geom3d

medianPlane is the next one I found. This one is also missing from the package documentation.

The function linePosition3d() is documented in geometry package, but is not installed in my windows distribution. I guess it was accidentally left out in the package creation process.
