Scilab fundamentals 3 - Create your first SciNote

    Although typing and executing commands on Scilab console is convenient and straightforward, these commands will not be saved after we exit Scilab environment. Therefore, SciNote is a script to save our Scilab commands.
The format of SciNote is a text file, and we can edit a SciNote file by a generic text editor. Scilab consists of a built-in SciNote editor by which we can edit SciNote files efficiently. Fig. 1 shows the icon to launch the SciNote editor, and Fig. 2 shows the interface of SciNote editor.

    Now we apply the material we learned in Scilabfundamentals 2 to create a SciNote file. First, type the following commands and then save this file as a sce file named exe_1.sce in the folder you installed Scilab program, i.e., C:\scilab-5.3.1.

 

// Scilab fundamental 3 clear; // clear all variables a = 1; // define a real variable, a b = 10; //  define a real variable, b c = 1+3*%i // define a complex number variable, c // d = a+b; e = exp(b); f = sin(2*a-b); // disp(d); // display variables on command line disp(e); disp(f);

 

    Before we execute this file, ensure the current directory is the path you save exe_1.sce. Fig. 3 shows how to set the current directory.

    Finally, just click the icon on top of SciNote editor, as shown in Fig. 4, to execute exe_1.sec. The values of d, e, and f will be shown on command line after execution, as shown in Fig. 5.
