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 | |
---|
39 | (3) Unpack Singular-1.1-share.tar.gz |
---|
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 $HOME/Singular/share/Singular'. |
---|
47 | If you use the bash, ksh, or sh shell, this can be |
---|
48 | accomplished by the command |
---|
49 | 'SINGULARPATH=$HOME/Singular/share/Singular;export SINGULARPATH' |
---|
50 | Furthermore, these commands should be put into your shell |
---|
51 | initialization file (e.g., $HOME/.tcshrc) |
---|
52 | |
---|
53 | Optional: |
---|
54 | (4) You may move the file singular.hlp contained in share/Singular to |
---|
55 | your info diretory (usually /usr/local/info) and add the line |
---|
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) |
---|
