 Hello friends, I am Naval Emul, working as an assistant professor in Mechanical Engineering department, Walsh and Institute of Technology, Solapur. In this video, we are going to study the introduction to SyLab Part 1, Learning Outcome. At the end of this session, students will be able to explain different mathematical functions of SyLab software, content, introduction to SyLab, MATLAB, history of SyLab, how to download and install SyLab references, introduction to SyLab, SyLab is pronounced as Sy that is scientific and lab that is laboratory. SyLab is a free and open-source cross-platform numerical computational package and a high-level numerically oriented programming language. SyLab is a free software alternative to MATLAB. It is free and open-source software. It is free and open-source software. Figure 1 shows the logo of the SyLab MATLAB. MATLAB believed to be used by over a million users in industry and academic appeared in late 1970s and has become a hot favorite of users who are either not skilled or simply uninterested in getting entangled with syntax of languages like C or Pascal even to solve a simple problem. MATLAB is a numerical computing environment and fourth generation programming language. It is developed by the MATWARKS. Among MATLAB's capabilities, the key is matrix manipulation. The name MATLAB itself is an acronym of matrix laboratory handling of functions and data, implementation of algorithm and creation of user interface. MATLAB is a proprietary software and a license fee is mandatory for its use. The free software movement attempts to offer technically, ethically superior and free alternative to proprietary softwares. There are many free open-source alternatives to MATLAB. In particular, SyLab is very popular. So Figure 2 shows you the window of the MATLAB. Free software. Wikipedia defines free software as follows. Free software or software liberal is software that can be used, studied and even modified without restriction and which can be copied and redistributed in modified or unmodified form either without any restrictions. Free software is available free of charge in most cases. It may be noted that there are currently alternative terms for free software such as software liberal, free and open source software that is called FOSS. SyLab is free and open source software that is called FOSS. A free software generally permits four kinds of freedom to its users. The freedom to run the software anywhere and anyway. Freedom to copy and distribute. The freedom to access to the source code of the software. The freedom to modify and redistribute. So we will see what is the history of SyLab. In 80s the CACSD that is Computer Aided Control System Design software was created at IRIA in France. Then at the beginning of 90s the software name changed to SyLab. It was then developed by the SyLab Group composed by six researchers from ENPC. SyLab 1.1 the first released version of SyLab was put on site on January 2, 1994. Think what is the necessity of SyLab? Why you should choose SyLab software? Think for few seconds pause the video. Okay let us see why it is necessary to use SyLab software. So the syntax of SyLab is very easy as compared to any other software like C and C++ or Java. SyLab is free software and it is easily available. Numerical problems can be expressed in a reduced number of code lines as compared to similar solution using traditional languages. There is a very large user community in SyLab that uses and supports SyLab by contributing in the form of mailing list, usenet groups with internet discussion system and their websites downloading and installing SyLab. It is very easy to download and install SyLab. So SyLab works and it is available for different platforms such as it works on window platform and Linux and Mac. The homepage of SyLab is www.sylab.org. So this is a homepage of SyLab. Once you open the homepage click on download. There are various options which are available for windows platform, Linux as well as Mac. You can click on that your file gets downloaded and just click on the downloaded file and run the file. The setup file will be installed in your PC or laptop and that SyLab is ready to use. So after installing the SyLab window it looks like this. So this is a freshly launched SyLab window. You can see the console window and above the console window there is a file menu which is described in the next video. So let us see the simple calculations on SyLab. What we can do on SyLab is with this example we clearly understand how simple the SyLab is. Suppose if we type x is equal to 5 and use semicolon followed by that then followed by enter then take y equal to 6 semicolon then followed by enter. Here the value of 5 is assigned to x and value of 6 is assigned to 5. Then if we multiply 5 and 6 just we need to type x into or asterisk y we get the result as 30. This operation is performed on the SyLab and the image of that is shown in the figure. So it is very simple just assign the value of x assign the value of 5 and the operation which we need that is x into y just type x into y you will get the answer. So we will see what are the different operators that are frequently used and accepted in SyLab. Plus sign for addition, minus sign for subtraction, asterisk sign or multiplication sign for multiplication. Then for division we use slash sign and raise 2 that is cap sign for power operations. So we have taken a few examples how we can use SyLab. So first we have taken addition, addition operator that is plus sign 5.5 plus 3.75 the answer is 9.25. In the same way we have taken a minus that is subtraction operator 6.0 minus 2.36 we get answer as 3.64. Just you may need to type 6.0 minus 2.36 then press enter you get the answer. In the same way we use for multiplication we use for division and we use for power also. Very simple just you need to type 2 raise to 6 and press enter you will get the answer as 64. All these operations are found in the SyLab and it is shown in a screenshot. So all the operations are performed. It is very simple and very easy as compared to the traditional languages like C and C plus plus. These are the references I have used. Thank you.
