<div dir="ltr"><div>Anyone here use/have an opinion about the <a href="http://rosettacode.org/wiki/Simple_Quaternion_type_and_operations#Python">Quaternion type @ rosettacode.org</a>? Or have an opinion about it having derived the type from collections.namedtuple? Anyone have an open-source, numpy-based alternative? Ditto last question for Octonion and/or general n-basis Grassmann (exterior) and/or Clifford Algebras? (rosettacode appears to have none of these). Thanks!<br>
