Scaling of 2D objects
MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.
MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Scale objects can scale several graphical objects simultaneously. Plotting the scale object renders all graphical objects inside.
Transformation objects can be used inside scale objects. If they are animated, the animations run simultaneously.
Animated scale objects are rather “cheap” concerning computing and storing costs. For more complex graphical objects, it is more efficient to use an animated scale object than to redefine the object for each frame.
