12: <p>
13: <a href="http://www.openxm.org">The OpenXM project </a>
14: provides a package of mathematical software systems,
15: which are integrated by
16: the OpenXM protocol.
17: OpenXM is an abbreviation of Open message eXchange for Mathematics.
18:
19: The computer algebra system
20: <a href="http://www.math.kobe-u.ac.jp/Asir/index.html">
21: Risa/Asir</a>
22: <img src="file:///usr/share/pixmaps/hopo_std_color.xpm"/>,
23: which is made in Japan,
24: is a main client of the package and
25: all software systems in the package can be used from Risa/Asir.

29: From the KDE menu, choose <br>

35: </font>
36: <br>
37: In order to use Asir(OpenXM),
38: your computer must be connected to the internet, because
39: a part of Risa/Asir is downloaded from ftp.math.kobe-u.ac.jp. <br>
40: <font color="cyan">
41: NOTE:
42: A part of Asir cannot be included in the CD because of a restriction
43: of the Risa/Asir license and the part is downloaded from the internet
44: after you agree with the license.
45: The size of the part is less than 2 Mega bytes.
46: The part is saved under your home directory
47: with the names .asir-tmp, .TeXmacs, .asirrc.
48: If you have a USB memory, you can save the files of your home directory
49: to the USB memory.
50: Choose the KDE menu <br>
51: knoppix --> configure --> create persistent home directory <br>
52: As to details, see a knoppix manual.
53: </font>
54: <br>
55: Once you downloaded, you can use Asir(OpenMX) from the TeXmacs, too.
56: In the TeXmacs menu, choose<br>

67: <h2> <font color="red"> What kind of computation can I do by Risa/Asir? </font> </h2>
68: Here are some examples
69: <ol>
70: <li> <font color="blue"> fctr(x^100-1); </font>
71: Factorization of x <sup> 100 </sup> - 1
72: <li> <font color="blue">
73: ifplot(x^3-y^2);
74: </font>
75: Drawing the zero set of x <sup> 3 </sup> - y <sup> 2 </sup> = 0.
76: <li> <font color="blue">
77: gnuplot.heat(0.0001,100);
78: </font>
79: Solving the heat equation by using the forward difference scheme.
80: The time step is 0.0001.
81: <li> <font color="blue">
82: dp_gr_main([x^2+y^2-4,x*y-1] | v=[x,y], order=[[x,1]]);
83: </font>
84: <br>
85: Computation of the Grobner basis of
86: x <sup> 2 </sup> +y <sup> 2 </sup> -4, x y -1
87: with the weight 1 for the variable x and the weight 0
88: for the variable y.
89: <li> <font color="blue">
90: F=[x^2+y^2-4,x*y-1]; V=[x,y];
91: dp_gr_main(map(dp_ptod,F,V) | v=V, order=[[x,1]]);
92: </font>
93: The same computation, but the answer is given by DP (distributed polynomial).
94: <li> Others:
95: A faster Grobner basis computation (nd_gr_main),
96: primary ideal decomposition (primadec), factorization in algebraic
97: extensions of Q (afctr), computation in the ring of differential operators
98: (*weyl*), number theoretic functions in pari, ...
