 I am Ilka Jagle, working as assistant professor in Wolchen Institute of Technology, Solabor. Today we are going to see introduction to SILAP learning outcome. At the end of this session, student will be able to recognize various toolbars of SILAP software. So, these are the contents of today's activity, free software, introduction to SILAP, environment of the SILAP, SILAP menu bar, SILAP features, SILAP operators, SILAP functions, SILAP toolbox. So, let's see what is a free software? Software is known as a free software, if it provides some kind of freedom. Our software generally provides a full kind of freedom to its user. First one, the freedom to run the software anywhere, anyway. Second, the freedom to copy and distribute. Third, the freedom to access to the source code and the freedom to access to the source code of the software. The freedom to modify and redistribute. So, let's see what is SILAP and what do you mean by SILAP? SILAP is pronounced as SILAP, that is scientific and lab laboratory. It is a free and open source software. It is user-friendly, numerical and computational package. SILAP is available for various operating systems, such as Windows, Linux and Max OS. So, you can find out, you can find free software on the website, www.silap.org and www.silap.in. So, figure one shows the SILAP logo. So, as we have discussed, SILAP is a free and open source software. SILAP was created in 1990 by the researchers and it was initially named as SILAP. Due to free availability, users can see and modify the source code, distribute and improve the source code and use the software for any purpose. So, due to the free availability, researchers, institutions and academic individuals can take the benefit of the SILAP software. I just want to ask you a question. So, you just think on why there is a necessity of SILAP or why you should choose the SILAP software. Just pause the video for few seconds and think what is the necessity of SILAP and why you should choose SILAP software. So, let's see, as we have discussed, it's a free and open source software. The syntax of the SILAP is very easy. Numerical problems can be easily solved with a reduced number of code lines as compared to traditional languages. There is a very large user community that uses and supports the SILAP by contributing in the form of mailing list, use net groups and websites. So, let's see the environment of SILAP. SILAP consists of mainly four windows, console window, editor window, graphics window and help window. So, let's see what is console window. So, console window is a window for the calculation work. Editor window is used to write the programs. Graphic window is used to plot the graphs. When you want to plot a graph, a new window pop-ups where you can see the graph plotted on that graphic window and help window. Here you can ask the queries which you are facing during the SILAP functioning or SILAP operations. And there's also an offline mode where you can ask the questions and you can see it's also have a function where you can function it very properly. So, this is how the console window of SILAP looks. So, here you see there's a variable browser comment history and there's a space for calculation work. This is the editor window of SILAP. Here, programs are written and the execution is done. So, graphics window of SILAP, 2D plot, 3D plots can be plotted on this graphic window. This is a help window of SILAP. If you have any doubt regarding any function, just type that function name in the search bar and you will get the detail of that functions in the help window. These are the SILAP menu bar. So, there are six menu bars in the SILAP. File menu, this is same as the other software packages which are used. Edit menu, in this edit menu, you can cut, copy, paste, select all, control menu. In this control menu, you can resume, interrupt or abort the functioning of the SILAP. Control preference menu. In this, the color, font and tool view bar history can be shown. Application menu. In this, there is SILAP 2 MATLAB converter and in this application menu, there is also a psychos SILAP 2 application. In the last menu, there, the last menu consists of the SILAP help. There you can, last menu, it consists of SILAP demonstrations which are very easy for the beginners who are trying the first time operation on the SILAP. These are the SILAP features. SILAP can perform many features such as arithmetic, relational, logical and matrix. Control systems, image and video processing, real-time and real-time control of hardware, interfacing data acquisition, simulation and plotting. SILAP can perform the following operations, arithmetic operations, relational or conditional operations, logical operations, matrix operation. The basic matrix operations like inverse, triangular, transpose, eigenvalues and eigenvector operations. So these are the SILAP functions. SILAP consists of many functions like elementary functions, mathematical functions, logical like and or not and complement trigonometric functions like sine, cos, tan, inverse trigonometric functions and hyperbolic functions. So these are the toolboxes which SILAP contributes. There are different toolboxes for different tasks such as SILAP image and video processing, psychos, labostrat, SILAP wavelet toolbox, SILAP java and dotnet module, SILAP remote access module. So these are the references, modeling and simulation in SILAP psychos by Stephen Campbell. This is a book and the book by Hema Chandran and Nair. Thank you.
