SciPy (pronounced "Sigh Pie") is open-source software for mathematics, science, and engineering. It is also the name of a very popular conference on scientific programming with Python. The SciPy library depends on NumPy , which provides convenient and fast N-dimensional array manipulation.

Interpolation (scipy.interpolate) — SciPy v0.11.dev Reference Guide (DRAFT)

There are several general interpolation facilities available in SciPy, for data in 1, 2, and higher dimensions:

http://docs.scipy.org/doc/scipy/reference/tutorial/interpolate.html

http://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.splrep.html#scipy.interpolate.splrep

Strictly positive rank-1 array of weights the same length as x and y. The weights are used in computing the weighted least-squares spline fit. If the errors in the y values have standard-deviation given by the vector d, then w should be 1/d.

interpolate.splrep — SciPy v0.11.dev Reference Guide (DRAFT)

If None (default), s=len(w) which should be a good value if 1/w[i] is an estimate of the standard deviation of y[i].

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting.

Celestia: Home

Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy. All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.

Stellarium ist ein kostenloses, quelloffenes Planetarium für ihren Rechner. Es zeigt einen realistischen 3D-Himmel, so wie man ihn mit bloßem Auge, Fernglas oder Teleskop sehen kann.

Octave

GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

Maxima, a Computer Algebra System

Maxima is a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions. The Maxima source code can be compiled on many systems, including Windows, Linux, and MacOS X. The source code for all systems and precompiled binaries for Windows and Linux are available at the SourceForge file manager .

To use MKL you will need to link the library at link time. To link to all the core libraries use -lmkl_solver -lmkl_lapack32 -lmkl_lapack64 -lmkl -lvml -lguide -lpthread . These are all dynamic libraries except mkl_solver , which contains sparse solver functions.
