Scilab is a free open source software for scientific modeling and simulation. It is a cross-platform software running on Windows, Linux, and macOS. It resembles many aspects of MATLAB with many built-in functions and tools to facilitate the modeling of natural and human systems.

The good
Free and open-source.
Integrated graphical editor (Xcos).
The user can create functions and scripts similar to MATLAB.
An active community of users from different disciplines.
Many built-in functions and numerical methods.
The bad
There is a lack of tutorials, learning resources and documentation compared to other open-source projects.

Scilab has an integrated graphical editor similar to MATLAB Simulink called Xcos. This feature is missing from many other projects such as GNU Octave.

Scilab comes loaded with functions and tools to make modeling any system as easy as it can get, this is the same philosophy of MATLAB. You will have powerful matrix manipulation functions plus a lot of numerical methods already implemented, in addition to advanced 2D and 3D plotting capabilities.

Maple's algebraic computation system (CAS) can be linked to extend Scilab's functionality to the area of symbolic mathematics, but because Maple is not free software, the other option is to interface to Maxima via a project called SciMax, but it remains limited to Linux machines at the time of writing this review. Another great tool that can be interfaced with Scilab is the Tcl/Tk scripting language.
