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 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 awailabel code.
To build the interface, you will need
- gsl-1.2 or better,
- python2.2 or better and
- NumPy, and
- a ANSI C compiler (i.e. gcc).
Retrieving the Interface:
You can download pygsl at 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 prefered 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 build # Running only python setup.py # can result in an error. So if you see an error runing setup.py please run python setup.py build # change to a id, that is allowed to do installation python setup.py install
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 requried 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
- 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
The directory test will contain several testsuites, based on python unittest. Change to this directory to run the tests.
What is implemented (versus gsl1.10):
What is not implemented yet (versus gsl1.10):
GSL Capabilites not yet wrapped by PyGSL
GSL Capabilites partly implemented
- Discrete Hankel Transforms
See also the 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.
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.
Please send mails to the pygsl mailinglist.
You can browse our cvs tree.
Type this to check out the actual version: cvs -d:pserver:firstname.lastname@example.org:/cvsroot/pygsl login Hit return for no password. cvs -z3 -d:pserver:email@example.com:/cvsroot/pygsl co pygsl
The script tools/extract_tool.py generates most of the special function code.
