First make up each frame in whatever way you can. Then use videoWriter() to make a movie. See attached demo.

Thanks a lot for the demo!

Do you know how to draw the 3D image in the gif as I attached? I think the video is made with some 3D images at different view, right?

Basically this called "animation" and there are several different ways how to perform it. You can find a lot of stuff at this page: https://www.mathworks.com/help/releases/R2019a/matlab/animation-1.html?container=jshelpbrowser

or in MATLAB type: web(fullfile(docroot, 'matlab/animation-1.html?container=jshelpbrowser')).

If you are interested exatly in creating a video file , look for a VideoWriter function in MATLAB help.
