clc

Clear Command Window

Syntax

clc

Description

example

clc clears all the text from the Command Window, resulting in a clear screen. After running clc, you cannot use the scroll bar in the Command Window to see previously displayed text. You can, however, use the up-arrow key ↑ in the Command Window to recall statements from the command history.

Use clc in a MATLAB® code file to always display output in the same starting position on the screen.

Examples

collapse all

Clear all text from the Command Window before running a command.
