Long ago I kind of (half)figured out how to deal with the package and
didn't find it practical/convenient.

So for myself I decided to switch to a more dedicated to symbolic 
calculations packages like 'maxima', 'fricas':

You can conduct symbolic manipulations in the above packages and import
into 'octave' the formulas they produce for heavy calculations. OTOH, the
packages can perform calculations too, but I do not know how comparable
with 'octave' they WRT performance.
