Save convhull as a stl file

clc;

Nf=40;

R=50;

sita=pi*rand(1,Nf);

fai=2*pi*rand(1,Nf);

x=R*(sin(sita).*cos(fai));

y=R*(sin(sita).*sin(fai));

z=R*cos(sita);

XYZ=[x' y' z'];

plot3(x,y,z,'r*')

axis equal

K = convhull(x,y,z);

trisurf(K,x,y,z,'Facecolor','cyan')

I hope to save the convhull I created as an STL file. Please help me. Thank you very much.

Use the above function.

I used the above function, but it can only be saved as a surface, not as a convex hull
