Getting started – First steps – Scilab. Content menu – 1 Overview – 2 First steps – 3 Plotting. In this section, we make our . There are several ways of using Scilab and the following paragraphs present three methods: . We also present the management of the graphical windows with the docking system. Finally, we present two major features of Scilab: the localization of Scilab, which provides messages and help pages in the language of the user, and the ATOMS system, a packaging system for external modules.

The console. The . This document is designed so that the Scilab examples which are printed here can be copied into the console. The goal is that the reader can experiment with Scilab behavior by himself. This is indeed a good way of understanding the behavior of the program and, most of the time, it is a quick and smooth way of performing the desired computation.

In the following example, the function disp is used in the interactive mode to print out the string ”Hello World!”.- -> s=! We only type the statement s=”Hello World!” with our keyboard and then hit the < Enter> key. Scilab answer is s = and Hello World!

The UCT eResearch Centre provides researchers with better and faster technology to manage, process and store their research data. Find out about high performance.

Then we type disp(s) and Scilab answer is Hello World! When we edit a command, we can use the keyboard, as with a regular editor.

Content menu – 1 Overview – 2 First steps – 3 Plotting. In this section, we present an overview of Scilab. Cross platform GUI for Maxima. Installing Fritzing. Please make sure your system satisfies one of these requirements: Windows - XP and up Mac - OSX 10.7 and up, though 10.6 might work too. JetBrains have generously supplied us with CLion licenses for the development of LibreCAD. This powerful IDE helps you develop in C and C++ on Linux, OS X and Windows.

We can use the left . Gold Hack For Gunbound Wc Download there. This lets us browse the previous commands by using the up .

In the following session, we type the statement disp in the console.- -> disp. Then we can type on the < Tab> key, which makes a list appear in the console, as presented in .

Scilab displays a listbox, where items correspond to all functions which begin with the letters ”disp”. We can then use the up and down arrow keys to select the function we want. Figure 4: The completion in the console.

The auto- completion works with functions, variables, . Figure 5 presents the editor during the editing of the previous ”Hello World!” example. Figure 5: The editor. The editor can be accessed from the menu of the console, under the Applications > Editor menu, or from the console, as presented in the following session.- -> editor()This editor manages several .

There are many features which are worth mentioning in this editor. The most commonly used features are under the Execute menu. This implies that the statements which do not end with the semicolon ”; ”character will produce an output in the console. The results which are produced in the console are only those which are associated with printing functions, such as disp for example. We can also select a few lines in the script, right click (or Cmd+Click under Mac), and get the context menu which is presented in .

This is the Edit > Correct Indentation feature, which automatically indents the current selection. This feature is extremely convenient, because it formats algorithms, so that the if, for and other structured blocks are easy to analyze. Figure 7: Context help in the editor. The editor provides a fast access to the inline help.

Indeed, assume that we have selected the disp statement, as presented in . When we right- click in the editor, we get the context menu, where the Help about ”disp” entry opens the help page associated with the disp function. Docking. The graphics in Scilab version 5 has been updated so that many components are now based on Java. This has a number of advantages, including the possibility to manage docking windows. The docking system uses Flexdock . Assume that we have both the console and the editor opened in our environment, as presented in . It might be annoying to manage two windows, because one may hide the other, so that we constantly have to move them around in order to actually see what happens.

Figure 8: The title bar in the source window. In order to dock the editor into the console, drag and drop the title bar of the editor into the console.

The Flexdock system allows us to drag and drop the editor into the console, so that we . All Scilab windows are dockable, including the console, the editor, the variable browser, the command history, the help and the plotting windows. To do this, we left- click on the title bar of the docking window, as indicated in .

Before releasing the click, let us move the mouse over the target window and notice that a window, surrounded by dotted lines is displayed. This ”phantom” window indicates the location of the future docked window. We can choose this location, which can be on the top, the bottom, the left or the right of the target window.

Once we have chosen the target location, we release the click, which . The round arrow in the title bar of the window undocks the window. The cross closes the window. We can also release the source window over the target window, which creates tabs, as in . Figure 1. 1 presents the state of this browser during a session.

Figure 1. 1: The variable browser. We can access this browser through the menu Applications > Variable Browser, but the function browsevar() has the same e. We can then interactively change the value of a variable by changing its content in a cell. On the other hand, if we change the variable content within the console, we must refresh the content of the dialog box by pushing the refresh button in the toolbar of the Variable Editor.

Figure 1. 2: The variable editor. The Command History dialog allows browsing through the commands that we have previously executed.

This dialog is available in the menu Applications > Command History and is presented in the . The right- click opens a context menu which lets us evaluate the command or edit it in the editor. Using exec. When several commands are to be executed, it may be more convenient to write these statements into a . To execute the commands located in such a . Several command line options are available and are presented in . Whatever the operating system is, binaries are located in the directory scilab- 5.

Command line options must be appended to the binary for the speci. The - nw option disables the display of the console. The - nwni option launches the nongraphics mode: in this mode, the console is not displayed and plotting functions are disabled (using them will generate an error). This executable corresponds to the icon which is available on the desktop after the installation of Scilab. The second executable is Scilex. With the Scilex. exe executable, the Java- based console is not loaded and the Windows terminal is directly used.

The Scilex. exe program is sensitive to the - nw and - nwni options. By default, the graphics mode is launched. The scilab script is sensitive to the - nw and - nwni options. There are two extra executables on Linux: scilab- cli and scilab- adv- cli. The scilab- adv- cli executable is equivalent to the - nw option, while the scilab- cli is equivalent to the - nwni option. Then we run the plot function in order to check that this function is not available in the non- graphics mode.

C: \Program Files\scilab- 5. Scilex. exe - nwni. Scilab 5. 5. 2 (Mar 3. Undefined variable: plot. Scilab instruction given in instruction- f . Assume that the content of the . To execute the demonstration under Windows, we created the directory ”C: \scripts” and wrote the statements in the .

The following session, executed from the MS Windows terminal, shows how to use the - f option to execute the previous script. Notice that we used the absolute path of the Scilex. C: \scripts>. To check that Scilab stays by default in interactive mode, we comment out the quit statement with the ”//”syntax, as in the following script. To exit, we interactively type the quit() statement in the terminal.

Localization. By default, Scilab provides its messages and its help pages in the English language. But it can also provide them in French, in Chinese, in Portuguese and in several other languages.

In this section, we review these features and see their e. For some of these languages, the help pages of Scilab are (partially) translated, as indicated in the table. These functions are presented in the table 1. Returns the default language used by Scilab.
