In this way, Scilab can be used as an interactive mathematical shell. The simplest way to execute Scilab code is to type it in at the prompt, ->, in the graphical command window. Scilab syntax is largely based on the MATLAB language. The reason for this is that earlier versions' licenses prohibited commercial distribution of modified versions of Scilab. Prior to version 5, Scilab was semi-free software according to the nomenclature of the Free Software Foundation. Scilab family 5 is distributed under the GPL-compatible CeCILL license. Due to the open source nature of the software, some user contributions have been integrated into the main program. Scilab is available free of cost under an open source license. Xcos is the open source equivalent to Simulink from the MathWorks.Īs the syntax of Scilab is similar to MATLAB, Scilab includes a source code translator for assisting the conversion of code from MATLAB to Scilab. Scilab also includes a free package called Xcos (based on Scicos) for modeling and simulation of explicit and implicit dynamical systems, including both continuous and discrete sub-systems. The software can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, and numerical optimization. While the language provides simple matrix operations such as multiplication, the Scilab package also provides a library of high-level operations such as correlation and complex multidimensional arithmetic. This allows users to rapidly construct models for a range of mathematical problems. By using matrix-based computation, dynamic typing, and automatic memory management, many numerical problems may be expressed in a reduced number of code lines, as compared to similar solutions using traditional languages, such as Fortran, C, or C++. The language provides an interpreted programming environment, with matrices as the main data type. Thanks to its ability to interconnect with third-party technologies and applications, Scilab can also act as a unique platform to bring together codes written in different programming languages in a single, unified language, thus facilitating their distribution, their back-up and use.Scilab is a high-level, numerically oriented programming language.
