Python library for scientific computing

 SciTools is a Python package containing lots of useful tools for scientific
 computing in Python. The package is built on top of other widely used
 packages such as NumPy, SciPy, ScientificPython, Gnuplot, etc.
 .
 SciTools also comes with a plotting interface called Easyviz, which is a
 unified interface to various packages for scientific visualization and
 plotting. Both curve plots and more advanced 2D/3D visualization of scalar
 and vector fields are supported. The Easyviz interface was designed with
 three ideas in mind: 1) a simple, Matlab-like syntax; 2) a unified interface
 to lots of visualization engines (backends): Gnuplot, Matplotlib, Grace,
 Veusz, Pmw.Blt.Graph, PyX, Matlab, VTK, VisIt, OpenDX; and 3) a minimalistic
 interface which offers only basic control of plots: curves, linestyles,
 legends, title, axis extent and names. More fine-tuning of plots can be done
 by adding backend-specific commands.
