SAGE 2.4.2

SAGE is a tool designed to help you studying a huge range of mathematics, including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, and exact linear algebra.
SAGE makes it easy for you to use most mathematics software together. SAGE includes interfaces to Magma, Mathematica, MATLAB, and MuPAD, and the free programs Axiom, GAP, GP/PARI, Macaulay2, Maxima, Octave, and Singular.
You work with SAGE using the highly regarded scripting language Python instead of an obscure language designed for a particular mathematics program. You can write programs that combine serious mathematics with anything else.
Use SAGE from your web browser, which connects either to a program running on your computer, or a program running elsewhere. With the SAGE notebook you can create embedded graphics, beautifully typeset mathematical expressions, add and delete input, and start up and interrupt multiple calculations.
Enhancements:
- r bradshaw: very very fast sagex new implementation of graph plotting code.
- t boothby: added compression of javascript so notebook loads more quickly.
- r miller: optimization to graph automorphism code
- k minola and m albrecht: build fixes to linbox and sage_c_lib.
- y qiang: transitioned dsage to use sqlite; many minor bugfixes
- w stein: wrote a MuPAD interface for SAGE.
- w stein: added restore and reset commands to SAGE, to (mostly) reset the state of SAGE and all interfaces very very quickly without having to quit and restart SAGE.
- w stein: p-adic L-series (numerous improvements)
- c witty (referee by r bradshaw): improvements to floating point <---> rational conversions.
