* Improve the index.
* Describe the grammar (grammar.texi).
* More examples.
* Some things from NEWS that might not be documented yet:
* Expressions of the form
A(i,j) = x
where X is a scalar and the indices i and j define a matrix of
elements now work as you would expect rather than giving an error.
I am told that this is how Matlab 5.0 will behave when it is
released.
(assignment)
* Octave's parser now does some simple constant folding. This means
that expressions like 3*i are now evaluated only once, when a
function is compiled, and the right hand side of expressions like
a = [1,2;3,4] are treated as true matrix constants rather than
lists of elements which must be evaluated each time they are
needed.
(???)
* Octave now attempts to continue after floating point exceptions
or out-of-memory errors.
(???)
* If Octave crashes, it now attempts to save all user-defined
variables in a file named `octave-core' in the current directory
before exiting.
(???)
* The info reader is now a separate binary that runs as a
subprocess. You still need the info reader distributed with
Octave though, because there are some new command-line arguments
that are not yet available in the public release of Info.
(install)
* If it is present, Octave will now use an `ls-R' database file to
speed up recursive path searching. Octave looks for a file called
ls-R in the directory specified by the environment variable
OCTAVE_DB_DIR. If that is not set but the environment variable
OCTAVE_HOME is set, Octave looks in $OCTAVE_HOME/lib/octave.
Otherwise, Octave looks in the directory $datadir/octave (normally
/usr/local/lib/octave).
