sca – Execute Screen(‘CloseAll’);
This is just a convenience wrapper that allows you to save typing the long,
and frequently needed, command.

It also unhides the cursor if hidden, restores graphics card gamma tables if
they’ve been altered, and restores other low-level display system state, like
centering the mouse cursor on screen 0 of a multi-X-Screen Linux setup. For
Matlab it implements a workaround for Matlab Java GUI bugs related to resolution
switching and entering/leaving fullscreen display mode.
