Re: [Maxima-discuss] Dependencies and constantness

[Eduardo O. <edu...@gm...>]

Ouch! Shame on me!
This works...

  setdepends      (var,deps) :=
    if     equal(deps,[])    then (apply('declare,[var,constant]),
                                   apply('remove, [var,dependency]))
    elseif equal(deps,[var]) then (apply('remove, [var,constant]),
                                   apply('remove, [var,dependency]))
    else                          (apply('remove, [var,constant]),
                                   apply('depends,[var,deps]))$

  setdepends(a,[])$    diff(a);   /* 0 */
  setdepends(a,[a])$   diff(a);   /* del(a) */
  setdepends(a,[x,y])$ diff(a);   /* a_x dx + a_y dy */

Cheers & thanks,
  Eduardo
