9 <h4>Overview</h4> |
|
|
10 <p> |
|
|
11 Octave is a high-level language, primarily intended for numerical |
|
|
12 computations. It provides a convenient command line interface for |
|
|
13 solving linear and nonlinear problems numerically. |

30 <h4>Availability</h4> |
|
|
31 <p> |
|
|
32 The latest released version of Octave is always available via |
|
|
33 anonymous ftp from <a href="ftp://ftp.che.wisc.edu/pub/octave"> |
|
|
34 ftp.che.wisc.edu</a> in the directory /pub/octave. |
|
|
35 Complete source and binaries for several popular systems are |
|
|
36 available. |

39 <h4>Installation and Bugs</h4> |
|
|
40 <p> |
|
|
41 Octave requires approximately 25MB of disk storage to unpack and |
|
|
42 install (significantly less if you don't compile with debugging |
|
|
43 symbols). In order to build Octave, you will need a current version |
|
|
44 of g++, libg++, and GNU make. Octave is known to compile on the |
|
|
45 following systems: |
|
|
46 </p> |
|
|
47 |
|
|
48 <ul> |
|
|
49 <li>SPARCstation 2 SunOS 4.1.2</li> |
|
|
50 <li>IBM RS/6000 AIX 3.2.x</li> |
|
|
51 <li>DECstation 5000/240 Ultrix 4.2a</li> |
|
|
52 <li>i486 Linux</li> |
|
|
53 <li>i486 NetBSD (without IEEE floating point support)</li> |
|
|
54 <li>HP 9000/7xx HP-UX 9.x</li> |
|
|
55 <li>SGI Irix 4.04</li> |
|
|
56 <li>NeXT NeXTStep ?</li> |
|
|
57 </ul> |
|
|
58 |
|
|
59 <p> |
|
|
60 See the notes in the files INSTALL and INSTALL.OCTAVE for more |
|
|
61 specific installation instructions, including directions for |
|
|
62 installing Octave from a binary distribution. |
|
|
63 </p> |
|
|
64 |
|
|
65 <p> |
|
|
66 The file BUGS contains a recommended procedure for reporting bugs, as |
|
|
67 well as a list of known problems. |

|
70 <h4>Binary Distributions</h4> |
|
|
71 <p> |
|
|
72 Binary copies of Octave are now distributed for several popular Unix |
|
|
73 systems. To save disk space, the complete source code for Octave is |
|
|
74 no longer included with the binary distribution, but should be |
|
|
75 available in the same place as the binaries. If not, please contact |
|
|
76 bug-octave@bevo.che.wisc.edu. |
|
|
77 </p> |
|
|
78 |
|
|
79 <p> |
|
|
80 The file INSTALL.OCTAVE contains specific installation instructions, |
|
|
81 for installing Octave from a binary distribution. |
|

|
|
84 <h4>Implemenation</h4> |
|
|
85 <p> |
|
|
86 Octave is being developed with the Free Software Foundation's make, |
|
|
87 bison (a replacement for YACC), flex (a replacement for lex), gcc/g++, |
|
|
88 and libg++ on a SPARCstation II and a DECstation 5000/240. It should |
|
|
89 be possible to install it on any machine that runs GCC/G++. It may |
|
|
90 also be possible to install it using other implementations of these |
|
|
91 tools, but it will most certainly require much more work. Do yourself |
|
|
92 a favor and get the GNU development tools, either via anonymous ftp |
|
|
93 from prep.ai.mit.edu or by writing the Free Software Foundation, 675 |
|
|

|
|
95 </p> |
|
|
96 |
|
|
97 <p> |
|
|
98 The underlying numerical solvers are currently standard Fortran ones |
|
|
99 like Lapack, Linpack, Odepack, the Blas, etc., packaged in a library |
|
|
100 of C++ classes (see the files in the libcruft and liboctave |
|
|
101 subdirectories). If possible, the Fortran subroutines are compiled |
|
|
102 with the system's Fortran compiler, and called directly from the C++ |
|
|
103 functions. If that's not possible, they are translated with f2c and |
|
|
104 compiled with a C compiler. Better performance is usually achieved if |
|
|
105 the intermediate translation to C is avoided. |
|
|
106 </p> |
|
|
107 |
|
|
108 <p> |
|
|
109 The library of C++ classes may also be useful by itself. |
