Introduction
Scilab is very powerful, free, and open-source software that is used worldwide by people for scientific engineering and numerical calculations. Scilab was first created in 1990 by researchers from the National Institute for Research in Digital Science and Technology, Inria. It is situated in France. For the graphical user interface, Scilab used Tcl/Tk for versions prior to 5.x and Java for the newer versions.

Why Scilab?
- It’s a high-level programming language.
- It contains a large number of built-in functions which are organized in libraries called toolbox.
- Scilab is a freely distributed and open-source scientific software package.
- A powerful open computing environment for Engineering and Scientific applications.
- Scilab users can develop their own modules so that they can solve their particular problems.
- The Scilab language allows dynamically compiling and linking other languages such as C, C++, FORTRAN, etc.: this way, external libraries can be used as if they were a part of Scilab’s built-in features.
- Scilab also interfaces LabVIEW, a platform and development environment for a visual programming language from National Instruments.
- It can be used in different operating systems such as UNIX, Windows, Linux, Mac, etc.
- Scilab uses a matrix environment which is quite simple and easy to use.
- In Scilab, mathematical operations like addition, subtraction, division, and multiplication can be performed immediately without any delay.
- It can give integrated object-oriented 2-D and 3-D graphics with animation.
