# List of free mathematical software

The list below presents an absolutely arbitrary selection of software I know about that can be used for mathematical (mostly algebraic) computation. There are a lot of omissions since either I don't know about some apps or I don't consider them worth mentioning. As mentioned above, the selection is purely arbitrary, so please don't mail me about a java-based calculator you have happened to write that you wish to be included. I won't. Period.

#### General purpose

- Maxima — easy to use, good GUI, no support for finite fields;
- Reduce — not so good GUI as Maxima, finite fields partially supported, some rough edges;
- Axiom — very powerful, as user friendly as a pit-bull with headache;
- Sage — in theory it combines various other tools, huge;

#### Commutative algebra and algebraic geometry

#### Group theory

- GAP — the standard tool for computational group theory;
- Magnus — works with
**infinite** groups, strange UI;

#### Number theory

#### Numerical methods and statistics

- SciLab — my preferred;
- Octave — free Matlab clone;
- R — free S clone;
