Bugs item #530447, was opened at 20020315 15:10 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=530447&group_id=4933 Category: None Group: None >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Daniel Lemire (lemire) Assigned to: Nobody/Anonymous (nobody) >Summary: "ode" function exist only in documentation Initial Comment: Desolve works fine, but ode, while documented, doesn't exist as a function. Examples: (C6) ode(diff(f(x),x)=x,f(x)); d (D6) ode( (f(x)) = x, f(x)) dx (C7) desolve(diff(f(x),x)=x,f(x)); 2 x (D7) f(x) =  + f(0) 2 (C8) ode(diff(f(x),x)=x,f(x),x); d (D8) ode( (f(x)) = x, f(x), x) dx Info from file /usr/local/info/maxima.info:  Fonction: ODE (equation,y,x) a potpourri of Ordinary Differential solvers combined in such a way as to attempt more and more difficult methods as each fails. For example, the first attempt is with ODE2, so therefore, a user using ODE can assume he has all the capabilities of ODE2 at the very beginning and if he has been using ODE2 in programs they will still run if he substitutes ODE (the returned values, and calling sequence are identical). In addition, ODE has a number of user features which can assist an experienced ODE solver if the basic system cannot handle the equation. The equation is of the same form as required for ODE2 (which see) and the y and x are dependent and independent variables, as with ODE2. For more details, do PRINTFILE(ODE,USAGE,SHARE); .  >Comment By: Raymond Toy (rtoy) Date: 20020628 16:16 Message: Logged In: YES user_id=28849 Leave the docs in, but also say ode no longer exists in maxima.
