PyGSL: Python interface for GNU Scientific Library
Status of GSL-Library:
The gsl-library is since version 1.0 stable and for general use. Read more
about it at the [1]GSL homepage.
Status of this interface:
We are collecting implementations of parts of gsl. So the interface is not
complete. We are looking forward to contributions of new submodules, while
maintaining the available code.
Requirements:
To build the interface, you will need
• [2]gsl-1.13 or better,
• [3]python2.6 or better and
• [4]NumPy, and
• a ANSI C compiler (i.e. gcc).
Retrieving the Interface:
You can download pygsl at [5]http://pygsl.sourceforge.net
Installing GSL interface:
Uninstall the old version of pygsl
gsl-config must be on your path
gzip -d -c pygsl-x.y.z.tar.gz|tar xvf-
cd pygsl-x.y.z
#do this with your preferred python version
#to set the gsl location explicitly use setup.py --gsl-prefix=/path/to/gsl
#If your are using cvs, remove your build directory.
python setup.py config
python setup.py build
# Running only
python setup.py
# can result in an error. So if you see an error running setup.py please
run python setup.py build
# change to a id, that is allowed to do installation
python setup.py install
Ready....
Using pygsl
Do NOT test the interface in the distribution root directory! -- please
install it first and then change to the tests directory and execute python
run_test.py If you want to execute it in the distribution root directory,
please run python setup.py build_ext -i first! It will put the required
binary files into the pygsl directory.
Just write in python
import pygsl.sf
print "%g+/-%g"%pygsl.sf.erf(1)
or
import pygsl.rng
rng=pygsl.rng.rng()
print rng.gaussian(1.0)
You may set the environment variable LD_LIBRARY_PATH to find the gsl
shared object.
Uninstall GSL interface:
rm -r "python install path"/lib/python"version"/site-packages/pygsl
Supported Platforms:
• Linux with python2.* and gsl-1.x
• Mac OS X with python2.* and gsl-1.x
• Win32 with python2.* and gsl-1.x
but is supposed to compile and run on any posix platform
Currently it is being tested:
• python3.5 numpy1.9.2 and gsl-2.1 (on mac os x, fink)
The version 2.1.1 was tested with
• python2.6, numpy1.4 and gsl-1.13 (on linux redhat)
• python2.7 numpy1.8 and gsl-1.16 (on mac os x, fink)
• python3.4 numpy1.8 and gsl-1.16 (on linux debian stable)
Testing:
The directory test will contain several testsuites, based on python
unittest. Change to this directory to run the tests.
What is implemented (versus gsl2.1):
• Blas
• BSplines
• Chebyshev
• Combination
• Const
• Diff
• Eigen
• Fit
• Ieee
• Integrate
• Interpolation
• Interpolation2D
• Linalg
• Math
• Minimize
• Multifit
• Multifit_nlin
• Multimin
• Multiroots
• Odeiv
• Permutation
• Poly
• Qrng
• Rng
• Roots
• Siman
• Sf
• Spline
• Statistics
What is not implemented yet (versus gsl1.10):
• GSL Capabilites not yet wrapped by PyGSL
• Sorting
• N-tuples
• GSL Capabilites partly implemented
• Discrete Hankel Transforms
See also the [6]TODO file in the distribution.
For the exact function volume for a module, please type:
import pygsl.sf
dir(pygsl.sf)
You can do this with the other modules, too. The naming scheme is the same
as in gsl.
Documentation:
There will be a small reference, but the function reference can be found
in the doc strings and at the gsl-reference. See also the "examples"
directory.
Support:
Please send mails to [7]the pygsl mailinglist.
Developement:
You can browse our [8]git repository.
Type this to check out the actual version:
git clone ssh://schnizer@git.code.sf.net/p/pygsl/GitRepro pygsl
The script tools/extract_tool.py generates most of the special function
code.
ToDo:
See TODO.
