This is the structure , in this the pink lined part is the Y section.

We need to find the points where this Y section is formed. Also we may adress this as finding or identifying the point where three sides are intersecting.

We have node cooridnates

Also if we use triangulation , then how to differentiate between upsidedown Y and normal Y?

在 MATLAB Online 中打开

Use delaunay to form the delaunay triangulation and then freeBoundary to find which vertices are on the boundary. The vertices that are not on the boundary will be the 3-way intersections.

T=delaunay(allVertices);
[~,boundaryVertices]=freeBoundary(T);
intersections=setdiff(allVertices,boundaryVertices,'rows')  %all points minus boundary points

I don't know how you mean for us to interpret your figure. It doesn't look like the figure in your original post, and you now have both red and blue connections.
