Mapping matrix for 1D meshes — inla.mesh.1d.A • INLA

Calculates barycentric coordinates and weight matrices for inla.mesh.1d objects.

inla.mesh.1d.A(mesh, loc, weights = NULL, derivatives = NULL,
               method = c("linear", "nearest", "quadratic"))

inla.mesh.1d.bary(mesh, loc, method = c("linear", "nearest"))

Arguments

mesh: An inla.mesh.1d object.
loc: Coordinate values.
weights: Weights to be applied to the A matrix rows.
derivatives: If TRUE, also compute derivative weight matrices dA and d2A.
method: Interpolation method. If not specified for inla.mesh.1d.A (recommended), it is determined by the mesh basis function properties.
