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 use your data across multiple sessions, save it to a compressed
file with a
.mat extension called a MAT-file. You
can restore saved data by loading a MAT-file back into MATLAB.
For more information, see Save and Load Workspace Variables.

|Open workspace variable in Variables editor or other graphical editing tool|
Create, edit, and copy variables in the MATLAB workspace, in the Command Window or using the Workspace browser and Variables editor.
Save some or all variables in the current workspace and reload the variables later during the current MATLAB session, or during another session.
For each variable or object, the Workspace browser can display statistics such as the min, max, and mean, when relevant.
Set preferences for the Workspace browser and Variables editor.
There are several versions of MAT-files that each support an increasing set of features, starting with MAT-file Version 4.
If you have a function that loads data from a MAT-file and find that MATLAB does not return the expected results, check whether any variables in the MAT-file share the same name as a MATLAB function.
