| squareMesh_RL {SpatialfdaR} | R Documentation |
Generate a Triangulation of a Square.
Description
The square is subdivided into m internal squares. Within each internal square,
nodes are set at the corners. Each square is subdivided into two triangles by a
line either going from lower left to upper right if orientation="L", of by
a line from lower right to upper left is orientation="R".
Usage
squareMesh_RL(m=1,orientation="L")
Arguments
m |
The number of squares within the outer square. |
orientation |
The position of the lower corner of the diagonal line
subdividing each square. This must be either |
Details
The outer square has sides of length m. If another length $x > 0$ of the side
is required, this can easily be achieved by the command p = p*x/m.
Value
A named list containing locations of nodes and which nodes define the edge segments and the triangles. The members are:
p: A two-column matrix specifying the nodes of the mesh.
e: A two-column matrix of integers specifying which nodes define each edge segment.
t: A three-column matrix of integers specifying which nodes define each triangle in anti-clockwise order.
