How can you list all the variables in the workspace in MATLAB?

To list all the variables in the workspace in MATLAB, the correct approach is to use the who command. This command provides a simple and effective way to display the names of all variables currently stored in the workspace. When executed, it will return a list of variable names, allowing users to easily see what data they have available for manipulation or analysis.

The who command is particularly useful in larger projects or when working with multiple variables, as it helps to keep track of what is present in the workspace without cluttering the command window with unnecessary details. It also allows for an interactive way to manage variables, helping to ensure that users can access and utilize their data efficiently.
