INCA recommends the following free software for numerical computation. These free downloads are available for most computers. There are no cost or licensing issues, which limit the use of commercial products. Please submit other suggestions using the E-Mail page on this website.

  • Octave 

    GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

Python Numarray provides array manipulation and computational capabilities similar to those found in IDL, Matlab, or Octave. Using numarray, it is possible to write many efficient numerical data processing applications directly in Python without using any C, C++ or Fortran code (as well as doing such analysis interactively within Python or PyRAF). For algorithms that are not well suited for efficient computation using array facilities it is possible to write C functions (and eventually Fortran) that can    read and write numarray arrays that can be called from Python.

Scilab is a scientific software package for numerical computations providing a powerful open     computing environment for engineering and scientific applications. Developed since 1990 by researchers from INRIA and ENPC, it is now maintained and developed by Scilab Consortium since its creation in May 2003.  Distributed freely and open source (see the license) via the Internet since 1994, Scilab is currently being used in educational and industrial environments around the world.
