Re: [Maxima-discuss] complete_square

[Barton W. <wi...@un...>]

  1.  Experiment with replacing ev(b_vec[i,1], map(lambda([avar], avar=0), vars)) with  subst(map(lambda([avar], avar=0), vars), b_vec[i,1]) .
The subst function has clean semantics, but ev doesn't.

  2.  Likely b_vec and c_mat should be declared local; see for example, Robert Dodier<http://search.gmane.org/?author=Robert+Dodier&sort=date> | 19 Jun 16:50 2008 on
