geom0, geom1, geom2, geom3
Purpose
geom0, geom1, geom2, geom3
Low-level constructor functions for geometry objects.
Syntax
Description
g = geom3(vertex,pvertex,edge,pedge,face,mfd,pcurve,...)
[g,...] = geom3(g3,...)
g = geom2(vertex,edge,curve)
[g,...] = geom2(g2,...)
g = geom1(p,ud)
[g,...] = geom1(g1,...)
g = geom0(p)
g3 = geom3(vertex,pvertex,edge,pedge,face,mfd,pcurve,...) creates a
geom3 object.
[g,...] = geom3(g3,...) coerces any 3D geometry object g3 to a geom3 object.
c = geom2(vertex,edge,curve,...) creates a geom2 object.
[g,...] = geom2(g2,...) coerces any 2D geometry object to a geom2 object.
c = geom1(vtx) creates a 1D geometry object from the property vtx.
[g,...] = geom1(g1,...) coerces any 1D geometry object to a geom1 object.
g = geom0(p) creates a 0D geometry object, where p is a matrix of size 0-by-1.
g = geom0(g1,...) coerces any 0D geometry object to a geom0 object.
The coercion functions accept the following property/values:

3D Geometry Object Properties
vertex is a 5-by-nv matrix representing the vertices of the 3D geometry. Rows 1,
2, and 3 provide the 3D coordinates of the vertices. Row 4 provides the subdomain
number. Row 5 contains a relative local tolerance for the entity. For non-tolerant
entities the tolerance is NaN.
pvertex is a 6-by-npv matrix containing embeddings of vertices in faces. Row 1
contains the vertex index (i.e. column in VERTEX), rows 2 and 3 contain (s,t)
coordinates of the vertex on the face, row 4 contains a face index, and row 5
contains the manifold index into mfd. Row 6 contains a relative local tolerance for
the entity.
