Octave version 0.71 is now available for ftp from ftp.che.utexas.edu
in the directory /pub/octave. Compressed and gzipped tar files are
available.
There have been a lot of changes in the way the files are organized,
so I'm not planning to make diffs this time.
With this release, Octave does not require a specially modified
version of gnuplot, so gnuplot sources are no longer distributed with
Octave. If you need a copy of gnuplot, its also available from
ftp.che.utexas.edu in the directory /pub/graphics.
Here's a summary of changes for version 0.71:
* Much improved plotting facility. With this release, Octave does
not require a specially modified version of gnuplot, so gnuplot
sources are no longer distributed with Octave. For a more
detailed description of the new plotting features, see the file
PLOTTING.
* New plotting commands:
plot -- 2D plots
semilogx -- 2D semilog plot with logscale on the x axis
semilogy -- 2D semilog plot with logscale on the y axis
loglog -- 2D log-log plot
mesh -- 3D mesh plot
meshdom -- create matrices for 3D plotting from two vectors
contour -- contour plots of 3D data
bar -- create bar graphs
stairs -- create stairstep plots
polar -- 2D plots from theta-R data
grid -- turn plot grid lines on or off
xlabel, ylabel -- place labels on the x and y axes of 2D plots
sombrero -- demonstrate 3D plotting
gplot -- 2D plot command with gnuplot-like syntax
gsplot -- 3D plot command with gnuplot-like syntax
set -- set plot options with gnuplot syntax
show -- show plot options with gnuplot syntax
closeplot -- close stream to gnuplot process
purge_tmp_files -- delete temporary files created by plot command
* Other new commands:
ls, dir -- print a directory listing
shell_cmd -- execute shell commands
keyboard -- get input from keyboard, useful for debugging
menu -- display a menu of options and ask for input
fft -- fast fourier transform
ifft -- inverse fast fourier transform
* Strings may be enclosed in either single or double quote
characters. Double quote characters are not special within single
quote strings, and single quotes are not special within double
quote strings.
* Command name completion now works for M-file names too.
* Better help and usage messages for many functions.
* Help is now available for functions defined in M-files. The first
block of comments is taken as the text of the help message.
* Numerous changes in preparation to support dynamic loading of
object files with dld.
* Bug fixes to make solving DAEs with dassl actually work.
* The command `save file' now saves all variables in the named file.
* If do_fortran_indexing is 'true', indexing a scalar with
[1,1,1,...] (n times) replicates its value n times. The
orientation of the resulting vector depends on the value of
prefer_column_vectors.
* Things like [[1,2][3,4]] no longer cause core dumps, and invalid
input like [1,2;3,4,[5,6]] now produces a diagnositic message.
* The cd, save, and load commands now do tilde expansion.
* It's now possible to clear global variables and functions by name.
* Use of clear inside functions is now a parse error.
