bm_fmesher: Mapper for general 'fmesher' function space objects

In inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Mapper for general fmesher function space objects

Description

Creates a mapper for general fmesher function space objects.

Usage

bm_fmesher(mesh)

bru_mapper_fmesher(...)

## S3 method for class 'bm_fmesher'
ibm_n(mapper, ...)

## S3 method for class 'bm_fmesher'
ibm_values(mapper, ...)

## S3 method for class 'bm_fmesher'
ibm_jacobian(mapper, input, ...)

Arguments

mesh	An fmesher object to map, supported by fmesher::fm_basis⁠(mesh, input)⁠ and fmesher::fm_dof(mesh).
...	Arguments passed on to other methods
mapper	A mapper S3 object, inheriting from bru_mapper.
input	Data input for the mapper.

Details

Handles indexed mapping for all fmesher classes that support fm_dof() and fm_basis() methods. For non-indexed mapping of fm_mesh_1d objects, use bru_mapper(mesh, indexed = FALSE) which invokes the bru_mapper.fm_mesh_1d() method.

Value

A bm_fmesher object.
