Drawing a sphere inside a sphere?

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.

Excellent thank you

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

[Star Strider]

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!
