Function space definition objects for 1D SPDE models.

since 23.08.18. Use fmesher::fm_mesh_1d() instead.

Create a 1D mesh specification inla.mesh.1d object, that defines a function space for 1D SPDE models.

inla.mesh.1d(
  loc,
  interval = range(loc),
  boundary = NULL,
  degree = 1,
  free.clamped = FALSE,
  ...
)

inla.mesh.1d.fem(mesh)

Arguments

loc: B-spline knot locations.
interval: Interval domain endpoints.
boundary: Boundary condition specification. Valid conditions are c('neumann', 'dirichlet', 'free', 'cyclic'). Two separate values can be specified, one applied to each endpoint.
degree: The B-spline basis degree. Supported values are 0, 1, and 2.
free.clamped: If TRUE, for 'free' boundaries, clamp the basis functions to the interval endpoints.
...: Additional option, currently unused.
mesh: An inla.mesh.1d object
