algebra in octave?

[Huub van Niekerk]

Hi,

I'm practising maths for univ. and wonder if I can octave for "simple"
algebra like 3a³+b²? From what I read in the online manual about
algebra, it's matrix related.

Thanks.

Well, if by "algebra" you mean Serge Lang's book, then, no, Octave
isn't the best choice for that. ;-)

More seriously, I think you mean symbolic manipulations. You want to
type something like "expand( (a+b)^2);" and be told "a^2 + 2ab + b^2".
In that case, I recommend you look at Maxima[1] or go whole hog and
look at Sage[2], which is an interface to both Maxima and Octave and
does many other things of it is own.

I think "symbolic" package might do what you need - it uses "ginac" as its
engine.
