How to export stl file from triangles.

Hello,

I want to export a stl file from triangulated points. The outputs of my code are the points id contained in triangles (nx3 array) and the outwards normals of trianglesm (nx3 array).

I tried the functions stlwrite or surf2stl but the results are not good.

Thank you for your help!

Normally stl files contain the vertices, not the normals.
