G.1.3 External Packages
The following external packages are required:
- BLAS
- Basic Linear Algebra Subroutine library
(http://www.netlib.org/blas). Accelerated BLAS libraries such as
ATLAS (http://math-atlas.sourceforge.net) are recommeded for
better performance.
- LAPACK
- Linear Algebra Package (http://www.netlib.org/lapack).
- PCRE
- The Perl Compatible Regular Expression library (http://www.pcre.org).
The following external package is optional but strongly recommended:
- GNU Readline
- Command-line editing library (www.gnu.org/s/readline).
If you wish to build Octave without GNU readline installed, you must use
the --disable-readline
option when running the configure script.
The following external software packages are optional but recommended:
- ARPACK
- Library for the solution of large-scale eigenvalue problems
(http://forge.scilab.org/index.php/p/arpack-ng). ARPACK is
required to provide the functions
eigs
and svds
.
- cURL
- Library for transferring data with URL syntax
(http://curl.haxx.se). cURL is required to provide the
urlread
and urlwrite
functions and the ftp
class.
- FFTW3
- Library for computing discrete Fourier transforms
(http://www.fftw.org). FFTW3 is used to provide better
performance for functions that compute discrete Fourier transforms
(
fft
, ifft
, fft2
, etc.)
- FLTK
- Portable GUI toolkit (http://www.fltk.org). FLTK is currently
used to provide windows for Octave's OpenGL-based graphics functions.
- fontconfig
- Library for configuring and customizing font access
(http://www.freedesktop.org/wiki/Software/fontconfig). Fontconfig
is used to manage fonts for Octave's OpenGL-based graphics functions.
- FreeType
- Portable font engine (http://www.freetype.org). FreeType is used
to perform font rendering for Octave's OpenGL-based graphics functions.
- GLPK
- GNU Linear Programming Kit (http://www.gnu.org/software/glpk).
GPLK is required for the function
glpk
.
- gnuplot
- Interactive graphics program (http://www.gnuplot.info). gnuplot
is currently the default graphics renderer for Octave.
- GraphicsMagick++
- Image processing library (http://www.graphicsmagick.org).
GraphicsMagick++ is used to provide the
imread
and imwrite
functions.
- HDF5
- Library for manipulating portable data files
(http://www.hdfgroup.org/HDF5). HDF5 is required for Octave's
load
and save
commands to read and write HDF data files.
- OpenGL
- API for portable 2D and 3D graphics (http://www.opengl.org). An
OpenGL implementation is required to provide Octave's OpenGL-based
graphics functions. Octave's OpenGL-based graphics functions usually
outperform the gnuplot-based graphics functions because plot data can be
rendered directly instead of sending data and commands to gnuplot for
interpretation and rendering.
- Qhull
- Computational geometry library (http://www.qhull.org). Qhull is
required to provide the functions
convhull
, convhulln
,
delaunay
, delaunay3
, delaunayn
, voronoi
, and
voronoin
.
- QRUPDATE
- QR factorization updating library
(http://sourceforge.net/projects/qrupdate). QRUPDATE is used to
provide improved performance for the functions
qrdelete
,
qrinsert
, qrshift
, and qrupdate
.
- SuiteSparse
- Sparse matrix factorization library
(http://www.cise.ufl.edu/research/sparse/SuiteSparse).
SuiteSparse is required to provide sparse matrix factorizations and
solution of linear equations for sparse systems.
- zlib
- Data compression library (http://zlib.net). The zlib library is
required for Octave's
load
and save
commands to handle
compressed data, including Matlab v5 MAT files.
