GraphViz

Compare

  Analyzed 4 months ago

Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Automatic graph drawing has many important applications in software engineering, database and web design, networking, and in visual interfaces for many other domains. Graphviz is open ... [More] source graph visualization software. It has several main graph layout programs. See the gallery for some sample layouts. It also has web and interactive graphical interfaces, and auxiliary tools, libraries, and language bindings. [Less]

NumPy

Compare

  Analyzed about 21 hours ago

NumPy is the fundamental package for scientific computing with Python. It contains among other things: a powerful N-dimensional array object sophisticated (broadcasting) functions tools for integrating C/C++ and Fortran code useful linear algebra, Fourier transform, and random number ... [More] capabilities Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases. NumPy is licensed under the BSD license, enabling reuse with few restrictions. [Less]

gnuplot

Compare

  Analyzed 1 day ago

gnuplot plots 2d and 3d graphs, from a data file or with a formula. It has an interactive mode with online help, or it can be used non-interactively. gnuplot does function fitting to data sets, and it does output to many terminals, among which are PostScript, X11 display, PNG, and GIF (via the old gd library).

R

Compare

  No analysis available

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different ... [More] implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. [Less]

Sage: Open Source Mathematics Software

Compare

  Analyzed about 19 hours ago

Sage is mathematical software, very much in the same vein as MATLAB, MAGMA, Maple, and Mathematica. Unlike these systems, every component of Sage is GPL-compatible. The interpretative language of Sage is Python, a mainstream programming language. Use Sage for studying a huge range of mathematics ... [More] , including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, and exact linear algebra. It is available for download from sagemath.org and its mirrors in source or binary form. If you have any questions and/or problems please report them to the Google groups sage-devel or sage-support. You can also drop by in #sagemath on freenode IRC. [Less]

Eigen

Compare

  Analyzed about 11 hours ago

Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. * It supports tiny & large dense, and sparse matrices, fully integrated with one another. * It has no dependency and no binary to compile or link-to. * It takes full advantage of ... [More] expression templates to provide a great API, and enable many optimizations including temporary removal, and intelligent explicit vectorization (SSE, AVX, AltiVec, and NEON). * Performance is on par with the best BLAS implementations. * It provides linear solvers comparable to LAPACK as well as sparse direct and iterative methods with preconditioners. * It keeps in mind the real needs of applications, for example the geometry features needed for 3D graphics.
