The MATLAB platform after creating, editing, saving and running the script test_hello.m looks as shown. help – If you type help followed by the name of a command or function, the corresponding help page is displayed.That is used to display floating point numbers in the command window with double precision. Another useful format command is format long, format compact – Compactifies the command window output.Useful when you want to start over with a clean slate. clc – Clears command window (instructions and output).Useful for example when you run multiple scripts that use the same variable names. You can delete selected variables or all variables. To keep a clean and organized workspace and command window. Generate any output in the command window.īefore starting to explore the MATLAB language, it is useful to learn some commands that are needed frequently If terminated with a semicolon, a statement will not
MATLAB statements can be terminated with a semicolon or not. MATLAB statements are expressions or assignments, variable declarations, operations with variables, input- or output-instructions,Ĭontrol flow statements or function calls, that perform specific tasks (plots, mathematical computations etc.). MATLAB scripts are created using the menu items in the EDITOR > FILE menu (New, Open, Save etc.)Īnd are executed using the menu items in the EDITOR > RUN-Menu (Run, Run and Advance, Run Section). Valid names are for example myscript1.m, myscript2.m, myfun1.m, myfun2.m. MATLAB script names may contain only letters, numbers and subscript. m, that contains the statements and comments of the program. MATLAB LiveScripts can be used as teaching tool and for demonstration purpose, since they convey a better understanding of the steps, commands and functions used to solve a problem.Ī MATLAB script is a text file with the extension.
#MATLAB TUTORIAL CODE#
While a pure code script is more efficient when the task is to solve a specific problem, The effect of a change in the source code can be seen directly and immediately in the output results (graphics, text output, etc.).

In a LiveScript, user input, source code and output including graphics are displayed in one single interactive window. m-file contains source code and comments and displays output in the command window and figures in the figure editor,Ī LiveScript (.mlx file) offers more functionality. MATLAB LiveScripts are a special type of scripts with extended documentation features. The folder can be anywhere on your computer but must be added to the MATLAB path by using HOME > Set Path Menu. Larger MATLAB programs are collections of MATLAB scripts stored in a common folder. Interactive mode is useful for tutorials and for testing small program parts. Output is also shown in the command window. MATLAB can be used in interactive mode, by entering commands directly in the command window. Command Window: displays commands and the output of statements.Ī MATLAB program can be created in different ways:.The actual programming is done in the editor. Editor: displays the contents of the script files.Command history: displays the history of commands.Workspace: displays the variables and functions of the running scripts.Here you create new folders and new scripts. File Browser: displays the folders that contain m-files.Octave IDE similarly is organized in five main windows, that are used for developing and running scripts. The only way to do this, is by undocking the command window, resizing it, and placing it on top of the main window. When running scripts, it is often required to see editor and output next to each other. You can see either the command window or the editor, but not both at the same time, Left part of the main view and command window, documentation, editor and variable editor in the right part of the In Octave, the default window layout organizes file browser, workspace and command history in the In a 4x4 grid, and be configured and aligned differently using the Layout menu. In MATLAB, the default window layout displays file browser, workspace, editor and command window In the following we use the term integrated development environments (IDE) and refer to "MATLAB IDE" and "Octave IDE".Īfter installation, the IDE's should look similarly as in the screenshots below.
#MATLAB TUTORIAL INSTALL#
In order to run MATLAB scripts, a MATLAB installation is required, a test version is downloadable from the Mathworks website.Īlternatively, you can download and install Octave,
