Is it possible to draw a sphere inside a sphere? I tried the following, but this covers the small sphere, despite the "mesh" instead of "surf":

[x,y,z] = sphere();

r = 5;

mesh( r*x, r*y, r*z );

hold on

r = 2;

mesh( r*x, r*y, r*z );

hold off

You can add

alpha(0.5)

after you plot the first one.

Sorry, i'm new to Matlab. I have a question. What is "alpha" for?

It’s the patch transparency parameter, now called FaceAlpha.

Another possible solution is to simply add

hidden off

to the very end of your code.

Works, thank you!
