Are you referring to a precise guideline of the publication you have
in mind, and if so, could you point to it ?
Depending on the meaning you put behind numerical stability, numpy may
or may not be stable. I would say it is not fundamentally different
than any similar numerical package (e.g. matlab, octave, etc...), as
they share a lot of the same underlying implementation for fundamental
algorithms. Incidentally, a lot of this common implementation is taken
from netlib, and the quality of the code there is variable.
If you are implementing new algorithms, I think it is fair to say that
the stability depends as much if not more from how you use a library
than the library itself.
