From help-request at octave dot org Thu Feb 3 15:27:04 2005 Subject: Re: differential and integral calculus From: "Henry F. Mollet" To: Andreas Volz , Octave_post Date: Thu, 03 Feb 2005 13:37:11 -0800 Octave is a numerical program not a symbolic program, if this is the correct terminology. Symbolic programs exist and they will probably do the things you would like to do.
