Dear all,

I am plotting a closed potato-shaped surface using "patch", then adding some tangent planes using

plane=surf(x,y,z)

But when I am plotting the normals of those planes, using

normals=plane.FaceNormals

some of them are pointing "inwards" towards the potato, while others point outward away from it. How can I make them all point away from the surface (or the center) of the potato?

Thank you kindly!Dear all,
