8 GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language. 8 GNU Octave is a high-level language,

10 Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages. 16 Octave has extensive tools for solving common numerical linear algebra problems,

18 Octave was originally conceived (in about 1988) to be companion software for an undergraduate-level textbook on chemical reactor design being written by James B. Rawlings of the University of Wisconsin-Madison and John G. Ekerdt of the University of Texas. We originally envisioned some very specialized tools for the solution of chemical reactor design problems. Later, after seeing the limitations of that approach, we opted to attempt to build a much more flexible tool. 38 Octave was originally conceived (in about 1988) to be companion software

20 There were still some people who said that we should just be using Fortran instead, because it is the computer language of engineering, but every time we had tried that, the students spent far too much time trying to figure out why their Fortran code failed and not enough time learning about chemical engineering. We believed that with an interactive environment like Octave, most students would be able to pick up the basics quickly, and begin using it confidently in just a few hours. 47 There were still some people who said

22 Full-time development began in the Spring of 1992. The first alpha release was January 4, 1993, and version 1.0 was released February 17, 1994. Since then, Octave has been through several major revisions, is included with Debian GNU/Linux and SuSE Linux distributions, and was reviewed in the in the July, 1997 issue of the Linux Journal. 58 Full-time development began in the Spring of 1992.

24 Clearly, Octave is now much more than just another courseware package with limited utility beyond the classroom. Although our initial goals were somewhat vague, we knew that we wanted to create something that would enable students to solve realistic problems, and that they could use for many things other than chemical reactor design problems. Today, thousands of people worldwide are using Octave in teaching, research, and commercial applications. 65 Clearly, Octave is now much more than just another courseware package

26 Just about everyone thinks that the name Octave has something to do with music, but it is actually the name of one of the author's former professors who wrote a famous textbook on chemical reaction engineering, and who was also well known for his ability to do quick "back of the envelope" calculations. We hope that this software will make it possible for many people to do more ambitious computations just as easily. 75 Just about everyone thinks that the name Octave has something to do with music,
