Drawing tetrahedron with surface normals

5 views (last 30 days)
I have the following code to draw a tetrahedron:
x = [1 1 -1 -1]
y = [1 -1 1 -1]
z = [1 -1 -1 1]
t = [1 2 3; 1 2 4; 2 3 4; 1 3 4]
trisurf(t,x,y,z)
How do I also draw the surface normals?

You can use 'triangulation' and 'faceNormal' functions to draw the surface normals. Refer the below link for more information:
