Every function has its own function workspace. Each function workspace is separate from the base workspace and all other workspaces to protect the integrity of the data. Even local functions in a common file have their own workspaces. Variables specific to a function workspace are called local variables.
Description. The Command History window displays a log of statements that you ran in the current and previous MATLAB® sessions. The Command History lists the time and date of each session in the short date format for your operating system, followed by the statements from that session.
Run Functions in the Editor
- Create a function in a program file named myfunction. m .
- View the commands available for running the function by clicking Run on the Editor tab.
- Replace the text type code to run with an expression that allows you to run the function.
- Run the function by clicking Run or a specific run command from the drop-down list.
MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Data analysis, exploration, and visualization.
To open the Workspace browser if it is not currently visible, do one of the following:
- MATLAB Toolstrip: On the Home tab, in the Environment section, click Layout. Then, in the Show section, select Workspace.
- MATLAB command prompt: Enter workspace .
The MATLAB Command Window is the main window where you type commands directly to the MATLAB interpreter. The MATLAB Editor Window is a simple text editor where you can load, edit and save complete MATLAB programs.
Share Global Variable Between Function and Command Line
Assign a value to the global variable using the function that you defined in the previous example. Display the value of the global variable, x . Even though the variable is global, it is not accessible at the command line. Undefined function or variable 'x'.If you saved the workspace to a MAT-file during the session, then you can recover it by loading the MAT-file. If you were editing a file in the Editor when MATLAB terminated unexpectedly, and you had the backup feature enabled, then you should be able to recover changes you made to files you had not saved.
whos(' -file ','filename','var1','var2',) list the specified variables in the MAT-file filename . The wildcard character * can be used to display variables that match a pattern. s = who() returns a cell array containing the names of the variables in the workspace or file and assigns it to the variable s .

In the "Home" tab in the MATLAB toolstrip, click "Layout" and select "Default." This will return the MATLAB workspace to the default layout.To create a new workspace variable from an existing variable, in the Variables editor, select an element, data range, row, or column in an array, and then in the Variable tab, select New from Selection.

The workspace contains variables that you create or import into MATLAB from data files or other programs. You can view and edit the contents of the workspace in the Workspace browser or in the Command Window. For more information, see Create and Edit Variables. Workspace variables do not persist after you exit MATLAB.
To open the Workspace browser, select Workspace from the Desktop menu in the MATLAB desktop, or type workspace at the Command Window prompt. The Workspace browser opens. The Workspace browser shows the name of each variable, its value, its array size, its size in bytes, and the class.
To see all the variables currently in the workspace, call the who function. To view the current value of a variable, type the variable name in the Command Window. For the example, to see the value of a variable n , type n and press Enter. The Command Window displays the variable name and its value.
In software development, a workspace is a grouping of source code files that make up a larger unit, like a web page, website, or software program. In a graphical interface, a workspace is a grouping of application windows used by a window manager applications to help reduce clutter on the desktop screen.
For instance, if you wanted to change the drive from "C:" to "D:", you should type "d:" and then press Enter on your keyboard. To change the drive and the directory at the same time, use the cd command, followed by the "/d" switch.
The MATLAB® search path is a subset of all the folders in the file system. MATLAB uses the search path to locate files used with MathWorks® products efficiently. When files with the same name appear in multiple folders on the search path, MATLAB uses the one found in the folder nearest to the top of the search path.
In
MATLAB Online™, to
search for files in the current
folder, go to the Home tab and click the Go to File button.
Simple Search for File and Folder Names
- Click the search button in the current folder toolbar. The address bar becomes a search field.
- Type a portion of a file name.
- Press Enter.
Access Files
- Right-click the Toolbar, and select Customize to open the MATLAB Toolbar Preferences panel.
- Go to MATLAB > Toolbars.
- On the right-hand side, in Controls, select the Access MATLAB Drive files on this computer option.
- Click OK. MATLAB adds the button to the Toolbar.
cd displays the current folder. Therefore, if you use cd within a function, the folder change persists after MATLAB® finishes executing the function. oldFolder = cd( newFolder ) returns the existing current folder to oldFolder , and then it changes the current folder to newFolder .
