The symeig module contains a Python wrapper for the LAPACK functions to solve the standard and generalized eigenvalue problems for symmetric (hermitian) positive definite matrices. Those specialized algorithms give an important speed-up with respect to the generic LAPACK eigenvalue problem solver used by NumPy (linalg.eig and linalg.eigh).

SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python and does not require any external libraries.

The Unified Form Language (UFL) is a domain specific language for declaration of finite element discretizations of variational forms.

Viper is a minimalistic scientific plotter and run-time visualization module. Viper has support for visualizing meshes and solutions in DOLFIN.

Qalculate! is a multi-purpose desktop calculator. It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface.

qrupdate is a Fortran library for fast updates of QR and Cholesky decomposition. It was originally part of GNU-Octave.

QtiPlot is a free (GPL) platform independent data analysis and visualization application similar to the non-free Windows program Origin.

The purpose of this project is to develop a free (open source), platform independent alternative to Origin. QtiPlot is being actively improved, all your suggestions to our "wish to" list and all your contributions are most welcome! Features: * QtiPlot is fully scriptable via Python, which gives you the possibility to use powerfull existing scientific tools, such as SciPy * OpenGL based 3D Plotting * Publication quality 2D plots * Easy export of plots to vector formats (EPS, PS, PDF) and to other various image formats (BMP, JPG, PNG, TIFF etc ...) * Powerful and versatile spreadsheets and calculations in column-logic * Easy ASCII-Import/Export of single or multiple files * Linear and non-linear y=f(x) curve fitting and estimation of statistical errors of the fit-parameters * Multi-peak fitting with Gaussian and Lorentzian peak profiles * Data analysis: statistics, sorting, FFT, data smoothing (Savitzky-Golay, FFT smoothing, and moving window average), data filtering (low/high/band pass and band block filters), convolution/deconvolution, correlation, interpolation, numerical integration/differentiation, etc... * Matrices optimized for 3D plotting * Templates support: all the settings for plots (2D/3D), tables and matrixes can be saved to ASCII files and restored later on for a fast editing process * Project files based on folders, a powerful project explorer with extensive built-in features: drag and drop, searching facilities, etc...

Topaz is a graph plotting system for scientists and engineers. 1. Topaz has a powerful graph expression and functions such as least square method. Topaz provides almost all functions that you need to make a 2D scattering graph. 2. Topaz has a polished character based user interface. 3. Topaz has powerful macro language of "Topaz script", which is like Perl. You can expand topaz itself or you can perform batch jobs using topaz scripts. Topaz official Web Page.

QtOctave is a Qt4 based front-end for Octave.
