Octave-Forge is a central location for the collaborative development of packages for GNU Octave. The Octave-Forge packages expand Octave's core functionality by providing field specific features via Octave's package system. For example, image and signal processing, fuzzy logic, instrument control, and statistics packages are examples of individual Octave-Forge packages. GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Refer to www.octave.org for more information.

NOTES FOR SNOW LEOPARD USERS

1 - mkoctfile

Since OSX 10.6 the Apple shipped version of gcc builds by default 64bit binaries
As the libraries included with Octave.app version 3.2.3 are 32bit, you need to apply
the following patch in order for mkoctfile to work:

  1.1) open the folder /Applications in the finder
  1.2) right-click on Octave.app and select "show package contents"
  1.3) navigate to /Applications/Octave.app/Contents/Resources/bin
  1.4) right-click on the file "mkoctfile" and select "Open with -> Other ... -> TextEdit.app"
  1.5) right after the line:

     # along with this program; If not, see <http://www.gnu.org/licenses/>.

  add the lines 

     CFLAGS="-m32 ${CFLAGS}"
     FFLAGS="-m32 ${FFLAGS}"
     CPPFLAGS="-m32 ${CPPFLAGS}"
     CXXFLAGS="-m32 ${CXXFLAGS}"
     LDFLAGS="-m32 ${LDFLAGS}" 

  and save.

2 - Gnuplot.app

An update to system libraries introduced with OSX 10.6.5 has broken the functionality 
of the Gnuplot.app included with the Octave.app distribution, in order to use Gnuplot.app
on  OSX 10.6.5 and later, you can use the fix described below:

  2.1) open the folder /Applications in the finder
  2.2) right-click on Gnuplot.app and select "show package contents"
  2.3) navigate to /Applications/Gnuplot.app/Contents/Resources/bin
  2.4) right-click on the file "gnuplot" and select "Open with -> Other ... -> TextEdit.app"
  2.5) change the line:

     DYLD_LIBRARY_PATH="${ROOT}/lib:${DYLD_LIBRARY_PATH}"

  to 

     DYLD_LIBRARY_PATH="${ROOT}/lib"

  and save.

NOTES FOR LEOPARD USERS

An update to system libraries introduced with OSX 10.5.8 has broken the functionality 
of the Gnuplot.app included with the Octave.app distribution, in order to use Gnuplot.app
on  OSX 10.5.8 and later, you can use the same fix described above for OSX 10.6.5.
