Discrete Laplace-Beltrami operator associated with a triangle-mesh manifold
laplace_beltrami_operator(
manifold = NULL,
vertex_matrix = NULL,
triangle_matrix = NULL
)
manifold |
A list of length 2 with names 'vertex_matrix' and 'triangle_matrix'
like |
vertex_matrix |
3-by-N matrix denoting the position of the N vertices
defining the triangle-mesh manifold. Similar to argument |
triangle_matrix |
3-by-M matrix denoting the position of the M triangles
defining the triangle-mesh manifold. Elements of each column are indices of vertices
defining the triangle (i.e. indices are columns of the vertex_matrix). Similar to
argument |
Either supply manifold
argument OR vertex_matrix
and triangle_matrix
arguments.
sparse square matrix representing the discrete Laplace-Beltrami operator for the manifold
