Need Help Rotating 3D plot I was wondering if you guys can give me some guidances on how to create a plot rotation. I need to create a video of the plot rotate around any of the axis. The rotating command need to be within the code. So when I run the function it would create a plot then start to rotate without any other input from me.
Thanks Guys.

I think the easiest way is to write your figure for each angle to an animated GIF.

Start with omitting the useless "close all; clear all". Especially the last is a waste of time only. Please read an apply https://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup#answer_18099.
Do you want to rotate the axes or the objects only?

Perhaps you want something like this at the end of your code:
for AZ = 0:5:360
view(AZ, 30);
pause(0.1);
end
for EL = -90:2:90
view(45, EL);
pause(0.1);
end
The detail "around any of the axis" is not clear.
