It evaluates a FEM object the specified set of locations.
eval.FEM(FEM, locations, CPP_CODE = TRUE)A FEM object to be evaluated.
A 2-colums matrix with the spatial locations where the FEM object should be evaluated.
Boolean. If TRUE the computation relies on the C++ implementation of a Visibility Walk Algorithm (Devillers et al. 2001). This usually ensures a fast computation.
A matrix of numeric evaluations of the FEM object. Each row indicates the location where the evaluation has been taken, the column indicates the
function evaluated.
