gnuplot

Compare

  Analyzed 10 months 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).

Maxima -- GPL CAS based on DOE-MACSYMA

Compare

  Analyzed 3 days ago

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 ... [More] 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. [Less]

Sage: Open Source Mathematics Software

Compare

  Analyzed 3 days 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]

SymPy

Compare

  Analyzed about 2 months ago

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, except optionally for plotting support.

Eigen

Compare

  Analyzed 3 months 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.
