Potential error in documentation for function tsearchn
显示 更早的评论
Howdy,
the tsearchn function says that the argument TRI must be a triangulation from delaunayTriangulation. However, the triangulation alone is not accepted. Instead, the function needs TRI.connectivityList. Is this an error in the documentation or am I using the function wrong?

I agree that the documentation is a bit confusing. When it says that you need to specify a Delaunay triangulation for the TRI input, it is indeed looking for the matrix that you receive as the ConnectivityList of a delaunayTriangulation object. This function predates the introduction of the delaunayTriangulation object so it accepts the matrix, not the object. [The fact that the object is listed in the See Also doesn't help avoid confusion, either.]
I can see why you thought that it might accept a delaunayTriangulation, but it actually accepts a Delaunay triangulation. I'll ask the documentation staff to clarify this difference.
