The best Numerical Computation alternative to Mathematica is GNU Octave, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 50 alternatives to Mathematica and ten of them are Numerical Computation Software so hopefully you can find a suitable replacement. Other interesting Numerical Computation Software alternatives to Mathematica are Julia, Scilab, Wolfram Language and Calcpad.
Octave is a computer program for performing numerical computations which is mostly compatible with MATLAB . It is part of the GNU Project. It is free software under the terms of the GNU General Public License.
Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an...
It's an easy, powerful, really fast language which feels like a mix of Python and Ruby but runs like C. It comes with many mathematical functions, has a good stack of libraries for graphs (including Matplotlib as PyPlot) and can be used with the Jupyter Notebook. Still not at version 1.0, but already a great tool!
Scilab is free and open source software for numerical computation providing a powerful computing environment for engineering and scientific applications. Scilab includes hundreds of mathematical functions.
Wolfram Language is a symbolic language, deliberately designed with the breadth and unity needed to develop powerful programs quickly. By integrating high-level forms—like Image, GeoPolygon or Molecule—along with advanced superfunctions—such as ImageIdentify or...
Calcpad is a lightweight mathematical platform for cloud and desktop. It parses simple text scripts and converts them into professional Html reports. Supports complex numbers, variables, functions, graphing, units and numerical methods.
Maple Flow is a mathematics tool that makes it easy for engineers to brainstorm, develop, and document their design calculations. It combines a simple, freeform interface with a comprehensive math engine and provides a whiteboard-style environment that automatically keeps...
Python(x,y) is a free scientific and engineering development software for numerical computations, data analysis and data visualization based on Python programming language, Qt graphical user interfaces and .
Doronix Math Toolbox is a numerical computing environment with programming language which can be used as alternative to MATLAB. It allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user functions, import and export CSV-files...
Reinteract is a system for interactive experimentation with Python. Reinteract worksheets contain Python code combined with the results of that code, formatted as text or graphical plots. Youu can go back and edit previously entered statements, and the results will update.
