| 7 | README FILE FOR SINGULAR SHARED DATA DISTRIBUTION |
---|
| 8 | ================================================= |
---|
| 9 | |
---|
| 10 | IMPORTANT: Please see the COPYING.share file contained in this directory |
---|
| 11 | for license information for the Singular shared (i.e. architecture |
---|
| 12 | independent data). |
---|
| 13 | |
---|
| 14 | This directory contains the following subdirectories |
---|
| 15 | 'share/Singular' -- contains Singular library files and compute tables |
---|
| 16 | 'share/Singular/docs' -- contains dvi files of singular documentation |
---|
| 17 | 'info' -- contains Singular's info help file |
---|
| 18 | |
---|
| 19 | and the file |
---|
| 20 | 'COPYING.share' -- for licence and copying information information |
---|
| 21 | |
---|
| 22 | Note that this distribution does not contain the Singular |
---|
| 23 | binaries. Instead, it contains architecture-independent data (such as |
---|
| 24 | Singular's program libraries written in Singular's programming |
---|
| 25 | language). See below for information on how to obtain the Singular |
---|
| 26 | executable program. |
---|
| 27 | |
---|
| 28 | Installing the Singular executable program |
---|
| 29 | ========================================== |
---|
| 30 | |
---|
| 31 | In order to use Singular, you |
---|
| 32 | |
---|
| 33 | (1) need to obtain the suitable binary Singular program for your |
---|
| 34 | architecture. |
---|
| 35 | |
---|
| 36 | (2) Uncompress the binary and install it at an appropriate place in |
---|
| 37 | your executable path (e.g., /usr/local/bin) |
---|
| 38 | |
---|
[057fd3] | 39 | (3) Unpack Singular-1.1-share.tar.gz |
---|
[4d2aefb] | 40 | (a) in the directory /usr/local/, or |
---|
| 41 | (b) in another directory, say, $HOME/Singular, and set the environment |
---|
| 42 | variable SINGULARPATH to the subdirectory |
---|
| 43 | $HOME/Singular/share/Singular |
---|
| 44 | If you use the tcsh or csh shell, this can be accomplished by |
---|
| 45 | the command |
---|
| 46 | 'setenv SINGULARPATH $HOME/Singular/share/Singular'. |
---|
| 47 | If you use the bash, ksh, or sh shell, this can be |
---|
| 48 | accomplished by the command |
---|
[5b930a] | 49 | 'SINGULARPATH=$HOME/Singular/share/Singular;export SINGULARPATH' |
---|
| 50 | Furthermore, these commands should be put into your shell |
---|
| 51 | initialization file (e.g., $HOME/.tcshrc) |
---|
[4d2aefb] | 52 | |
---|
| 53 | Optional: |
---|
| 54 | (4) You may move the file singular.hlp contained in share/Singular to |
---|
[5b930a] | 55 | your info diretory (usually /usr/local/info) and add the line |
---|
[4d2aefb] | 56 | * Singular: (singular.hlp). The Singular manual |
---|
| 57 | to the 'dir' file contained in your info directory. |
---|
| 58 | |
---|
| 59 | (5) You may print the Singular manual (contained in docs/singular.dvi) |
---|
| 60 | and tutorial (contained in docs/tutorial.dvi). |
---|
| 61 | |
---|
| 62 | Overview of Singular |
---|
| 63 | ==================== |
---|
| 64 | Singular is a special-purpose computer algebra system for commutative |
---|
| 65 | algebra, algebraic geometry and singularity theory. The main features |
---|
| 66 | of Singular are: |
---|
| 67 | |
---|
| 68 | * Computations in very general rings (polynomial rings, localizations |
---|
| 69 | of rings at a prime ideal, tensor products of rings) over many |
---|
| 70 | ground fields (rational numbers, mod p numbers, Galois fields, |
---|
| 71 | transcendental/algebraic extensions) and monomial orderings (all |
---|
| 72 | standard monomial orderings, including matrix orderings) |
---|
| 73 | |
---|
| 74 | * Very fast standard (resp. Groebner) bases computations |
---|
| 75 | |
---|
| 76 | * Polynomial factorization, resultant, and gcd computations |
---|
| 77 | |
---|
| 78 | * Large variety of implemented related algorithm: FGLM, |
---|
| 79 | Hilbert-driven, Factorizing Buchberger; Minimal resolutions, |
---|
| 80 | Primary decomposition; Usual ideal theoretic operations; standard |
---|
| 81 | combinatorial algorithms. |
---|
| 82 | |
---|
| 83 | * Efficient and flexible communication links based on the MP |
---|
| 84 | protocol and library |
---|
| 85 | |
---|
| 86 | * Easy-to-use, command-driven user-interface |
---|
| 87 | |
---|
| 88 | * Intuitive, C-like programming language |
---|
| 89 | |
---|
| 90 | * Extensive libraries of procedures, written in Singular's |
---|
| 91 | programming language |
---|
| 92 | |
---|
| 93 | * Written in C/C++. Available as binary program for common hard- and |
---|
| 94 | software platforms (including most Un*x variants, MS-DOG, MacOS) |
---|
| 95 | |
