I had a further play around with it. I added: ;C:\Program Files\Maxima-5.16.3\bin;C:\Octave\3.2.3_gcc-4.4.0\bin to the PATH prefix in the Preferences, and then restarted LyX.
Now when I type 4+5 in a math field and then use Edit->Math->CAS->Octave or ->Maxima it calculates the answer and sets the field to 4+5=9. And if I enter $\int_{0}^{1}x^{2}dx$ maxima will return the answer 1/3. That's a fantastic new discovery of a further LyX feature. As for making it more useful, perhaps LyX needs some buttons in the math toolbar for Octave or Maxima or a way of customizing some new buttons to run the Edit->Math->CAS options. 2009/11/24 Liviu Andronic <landronim...@gmail.com>: > On 11/24/09, Ken <kmai...@googlemail.com> wrote: >> I have maxima-5.16.3 and octave-3.2.3 installed on my Windows XP >> machine.
