- Matlab stands for ``Matrix Laboratory'', not for ``Mathematics Laboratory''. As such its usefulness becomes more apparent on small partial differential equations problems, which often result in operations on relatively small matrices.
- Octave is named after Prof. Octave Levenspiel, the author of ``Chemical Reaction Engineering'', New York, Wiley, 1972, 573 pp., ISBN 0471530166.
- Both systems derive their strengh from

`netlib.ornl.gov`. These libraries can be accessed from a Fortran program just as easily, but not interactively. We will cover some of those later in the course. - Octave documentation is available on-line through
our (OVPIT) Emacs, i.e., Emacs that lives in
`/afs/ovpit.indiana.edu`

,`info`.- Type
`M-x info`, or`C-h i`to bring up`info`. - Search down for the line:
* Octave: (octave). Interactive language for numerical computations. * Octave FAQs: (Octave-FAQ.info). Frequently Asked Questions about Octave. * Octave Library: (liboctave.info). About Octave's C++ library.

- Position your cursor on any of those and press return.

- Octave documentation can be also found in

and inhttp://beige.ucs.indiana.edu/PostScript/gnu/octave

There is a pointer to this directory on the OVPIT front page:`http://beige.ucs.indiana.edu`

. - We will explore Octave and Matlab more in the second part of the course, when we are going to talk about fields.
