Extract points from generated mesh
显示 更早的评论
I have the follwoing code:
clear all
clc
e2 = antenna.Ellipse('Majoraxis',4,'Minoraxis',2)
mesh(e2,'MaxEdgeLength',1e-1)
This creates a mesh something like this:
Is it possible to extract the nodal points as one large vector (or any other numeric form) from here on out? I require to do some further processing with the points.
Thanks

e2 = antenna.Ellipse('Majoraxis',4,'Minoraxis',2)
h = mesh(e2,'MaxEdgeLength',1e-1)
xyz = e2.Points .';
These are the points -- just the coordinates, no connection information.
tr = e2.Triangles;
This is the connection information, where each entry is a node number. Each column is a triangle. There are is an extra row of zeros for internal processing reasons.

The first triangle is xyz(781,:) joined to xyz(783,:) joined to xyz(741,:) and the 0 marks the end of the vertex list.
