25 Octave was originally intended to be companion software for an |
|
|
26 undergraduate-level textbook on chemical reactor design being written by |
|
|
27 James B. Rawlings of the University of Wisconsin-Madison and John |
|
|
28 G. Ekerdt of the University of Texas. |
|
|

|
|
30 Clearly, Octave is now much more than just another `courseware' package |
|
|
31 with limited utility beyond the classroom. Although our initial goals |
|
|
32 were somewhat vague, we knew that we wanted to create something that |
|
|
33 would enable students to solve realistic problems, and that they could |
|
|
34 use for many things other than chemical reactor design problems. |
|
|
35 |
|
|
36 There are those who would say that we should be teaching the students |
|
|
37 Fortran instead, because that is the computer language of engineering, |
|
|
38 but every time we have tried that, the students have spent far too much |
|
|
39 time trying to figure out why their Fortran code crashes and not enough |
|
|
40 time learning about chemical engineering. With Octave, most students |
|
|
41 pick up the basics quickly, and are using it confidently in just a few |
|
|
42 hours. |
|
|
43 |
|
|
44 Although it was originally intended to be used to teach reactor design, |
|
|
45 it has been used in several other undergraduate and graduate |
|
|
46 courses in the Chemical Engineering Department at the University of |
|
|
47 Texas, and the math department at the University of Texas has been using |
|
|
48 it for teaching differential equations and linear algebra as well. If |
|
|
49 you find it useful, please let us know. We are always interested to |
|
|
50 find out how Octave is being used in other places. |
|
|
51 |
|
|
52 Virtually everyone thinks that the name Octave has something to do with |
|
|
53 music, but it is actually the name of a former professor of mine who |
|
|
54 wrote a famous textbook on chemical reaction engineering, and who was |
|
|
55 also well known for his ability to do quick `back of the envelope' |
|
|
56 calculations. We hope that this software will make it possible for many |
|
|
57 people to do more ambitious computations just as easily. |
|
|
58 |
|
|
59 Everyone is encouraged to share this software with others under the |
|
|
60 terms of the GNU General Public License (@pxref{Copying}) as described |
|
|
61 at the beginning of this manual. You are also encouraged to help make |
|
|
62 Octave more useful by writing and contributing additional functions for |
|
|
63 it, and by reporting any problems you may have. |

|
|
151 |
|
|
152 There are a number of ways that you can contribute to help make Octave a |
|
|
153 better system. Perhaps the most important way to contribute is to write |
|
|
154 high-quality code for solving new problems, and to make your code freely |
|
|
155 available for others to use. |
|
|
156 |
|
|
157 If you find Octave useful, consider providing additional funding to |
|
|
158 continue its development. Even a modest amount of additional funding |
|
|
159 could make a significant difference in the amount of time that is |
|
|
160 available for development and support. |
|
|
161 |
|
|
162 If you cannot provide funding or contribute code, you can still help |
|
|
163 make Octave better and more reliable by reporting any bugs you find and |
|
|
164 by offering suggestions for ways to improve Octave. @xref{Trouble}, for |
|
|
165 tips on how to write useful bug reports. |

179 Octave is available on CD-ROM with various collections of other free |
