What about Roth-Hurwitz and the root-locus methods ?
Are you going to implement those on your future versions ?
Happy August holidays,

Aries ;-)

My thoughts:
For Root-Locus method i think Geometric App is a good candidate. but not animated enough to move points along a path. or move a set of conjugate pairs to its new locations.
Also too many rules associated with this method...nevertheless if done on Matlab is doable on temperament Prime.(just less real estate screen).

Roth-Hurwitz: i always wanted to implement that on prime...one of these days i will.
i tend to use Ackermann's method (space vector) for calculating sensitivity gain K.

Thanks toshk, great ideas and I'm looking forward to your updates ;-)
Best,

Aries :-)
