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. | |

38 Although it was originally intended to be used to teach reactor design, | |
39 it has been used in several other undergraduate and graduate | |
40 courses in the Chemical Engineering Department at the University of | |
41 Texas, and the math department at the University of Texas has been using | |

155 better system. Perhaps the most important way to contribute is to write | |
156 high-quality code for solving new problems, and to make your code freely | |

162 could make a significant difference in the amount of time that is | |
