Scilab

Freeware Scilab

Scilab is a powerful mathematical package for the construction of 2D and 3D graphs, solving linear problems, algebra with sparse matrix. It gives the possibility to use the interpolation and approximation, differential and non-differential optimization. The package also has a built-in language. read more...

SMath Studio

Freeware SMath Studio

SMath Studio is a good package for calculation, simplification of mathematical graph charting functions. The interface is very intuitive and very similar to MathCad. read more...

GNU Octave

Freeware GNU Octave

GNU Octave is cross-platfor software package for working with mathematical models and graphs. The software is written in the programming language C++ and can be implemented in other projects. The program supports a set of functions for solving mathematical problems, but if the user is not satisfied with its functionality, he can download add-ons. GNU Octave is compatible with such software as MATLAB and it supports many of its functions. read more...

Maxima

Freeware Maxima

Maxima, a Computer Algebra System, is a system for the manipulation of symbolic and numerical expressions. It was created in the programming language Common Lisp, the first launch of which took place back in 1982. This utility is designed for analytical and numerical calculations, as well as the formation of graphs of functions. This development has several graphical user interfaces (wxMaxima, XMaxima and other). The program provides the most accurate numerical calculations as applied fractions, whole numbers (as a floating-point arbitrary precision, and without it). It should be noted that by using pseudographics, the application can operate in batch mode. The system has a fairly intuitive interface, despite the fact that it can hardly be called modern. read more...

Graph Online

Freeware Graph Online

Graph Online is a free service designed for visualization of the graph and finding the shortest path on a graph. Creating a graph is carried out on the adjacency matrix and incidence matrix. Also, users can search for connected component. The service supports directed digraphs and undirected graphs (or ordinary graphs). Users may save built graph and continue working with it later. read more...
