- It's calc.el, an Emacs Lisp package. It is -amazing-.
- It can do mostly the same symbolic operations as Mathematica
- though it expects you to apply more manual control.
- Unlike Mathematica, it can display equations with superscripts,
- drawing radical signs etc. out of ascii characters, etc.
- It can differentiate, integrate, solve equations, do arithmetic
- with bignums, ratnums, complex numbers, matrices,
- etc. though the algorithms are not always as sophisiticated
- as programs like Mathematica. On the other hand, it is
- mroe convenient to use for simple things once you get used to
- it. It is set up like an calculator: most of the operations
- are bound to short keystroke combinations, there is an
- operand stack displayed on the screen etc.
-
- You can ftp it from prep.ai.mit.edu:pub/gnu/calc-2.02.tar.Z.
- You also need GNU Emacs, which you can get from the same place.
