Hi:
I'm an user of Octave. Do you have the manual for it? I had contacted
John Campbell about the specific problem I am trying to solve. John is sick
these days, so I need a help of how to operate the software properly.
The questions I have are following:
1. How do I load my experimental data into Octave?
2. Is there any special typing rules for Octave? There were a lot of
parse errors after I run Octave.
If you want to take a look of the error message of my running, please
let me know. My phone number is 471-6884 or e-mail address:
chiangcy@bashful.cc.utexas.edu
Thank you.

Subject: Octave version 0.75.1 released
Date: Fri, 17 Sep 93 18:39:47 EDT
From: John Eaton
Sender: help-octave-request
Octave version 0.75.1 is now available for ftp from ftp.che.utexas.edu
in the directory /pub/octave. Compressed and gzipped tar files are
available, as are diffs relative to version 0.74.
PLEASE NOTE: As of version 0.75, we are only distributing gzipped
files because we no longer have room to distribute both compressed
and gzipped files.
Binaries for DECstation and SPARCstation systems are available.
Binaries for other systems will be made available as time permits, or
as others make them available to us. If you would like help out by
making binaries available for other systems, please contact
bug-octave@che.utexas.edu.
Octave's Texinfo documentation is much more complete, but could
still use a lot of work. Any comments on the organization and
content, as well as any changes or corrections, are more than welcome.
If you are interested in working on the manual, please contact
bug-octave@che.utexas.edu.
Here's a summary of other changes for version 0.75:
* The history function now prints line numbers by default. The
command `history -q' will omit them.
* The clear function now accepts regular expressions.
* If gplot (or gsplot) are given strings to plot, and the string
names a file, Octave attempts to plot the contents of the file.
* New functions:
history:
run_history -- run commands from the history list.
edit_history -- edit commands from the history list with your
favorite editor.
linear algebra:
balance -- Balancing for algebraic and generalized
eigenvalue problems.
givens -- Givens rotation.
is_square -- Check to see if a matrix is square.
is_symmetric -- Check to see if a matrix is symmetric.
qzhess -- QZ decomposition of the matrix pencil (a - lambda b).
qzval -- Generalized eigenvalues for real matrices.
syl -- Sylvester equation solver.
control systems:
abcddim -- Check dimensions of linear dynamic system [A,B,C,D].
is_controllable -- Check to see if [A,B,C,D] is controllable.
is_observable -- Check to see if [A,B,C,D] is observable.
are -- Solve algebraic Ricatti equation.
dare -- Solve discrete-time algebraic Ricatti equation.
lqe -- Kalman filter design for continuous linear system.
lqr -- Linear Quadratic Regulator design.
lyap -- Solve Lyapunov equation.
dlyap -- Solve discrete Lyapunov equation.
tzero -- Compute the transmission zeros of [A,B,C,D].

Subject: Digest or FAQ?
Sender: help-octave-request
Hi,
Is there a digest or FAQ accociated with help-octave that might be
downloaded to avoid repeating well worn queries?
On octave development, has any consideration been given to extending
the syntax to handle more than two subscripts? There are lots of applications
where the "natural data structure" for numerical solution is three, four or
even higher dimensional arrays . One only need look at trying to handle
transfer function polynomial matrices ( the MATLAB control toolbox ) to
cringe at the gymnastics forced by a limitation to two dimensional arrays.
