Tools for data analysis and
data generation
When faster
numerical computation and/or greater
dimensional abstraction than native Python affords is needed, NumPy is
a "standard" by which other tools can be judged.

| Description |
|
NumPy
(Numeric Python) is an
extensive array data processing tools. It contains useful procedures
for numerical computation. It can be used for fast manipulation of
multi-dimensional arrays.

NumPy also supports a Fortran-to-Python interface generator and other
Fortran compiler tools. |

| Initial
Comments |
|
Many
scientific routines have been
written using these tools. Over its evolution, NumPy has also been
known as both Numeric and Numarray and references to it as such can be
found both in the documentation and in third-party code. Earlierthis
year (2007) there was some discussion on the Python SIG about reasons
for a Numeric package still being available, however I believe that for
those using it for the first time, NumPy is the correct package. In
fact some of the code examples in the package download still try to
"import numeric". I have yet to find an example which doesn't run if
"numeric" is replaced with "numpy" in the python code. |
Do you have other
suggestions for tools in this
category? For example, there there is also a Python interface to Matlab
called PyLab. See details on the matplotlib home page. If you'd like to
