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). + (install)
