R: Mapping matrix for 1D meshes

inla.mesh.1d.A {INLA}

R Documentation

Mapping matrix for 1D meshes

Description

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

Usage

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.
