R_eval.FEM.basis

An <code>FEMbasis</code> object representing the Finite Element basis; See <a href="/link/create.FEM.basis?package=fdaPDE&version=0.1-3" rd-options="" data-mini-rdoc="fdaPDE::create.FEM.basis">create.FEM.basis</a>.

FEMbasis

A 2-columns matrix with the spatial locations where the bases should be evaluated.

locations

A vector of lenght 2 specifying the order of the partial derivatives of the bases to be evaluated. The vectors' entries can
be 0,1 or 2, where 0 indicates that only the basis functions, and not their derivatives, should be evaluated.

nderivs

Only executed when the function <code>smooth.FEM.basis</code> is run with the option <code>CPP_CODE</code> = <code>FALSE</code>. It evaluates the Finite Element basis functions and their derivatives up to order 2 at the specified set of locations. 
This version of the function is implemented using only R code. It is called by <a href="/link/R_smooth.FEM.basis?package=fdaPDE&version=0.1-3" rd-options="" data-mini-rdoc="fdaPDE::R_smooth.FEM.basis">R_smooth.FEM.basis</a>.

An implementation of regression models with partial differential regularizations, making use of the Finite Element Method. The models efficiently handle data distributed over irregularly shaped domains and can comply with various conditions at the boundaries of the domain. A priori information about the spatial structure of the phenomenon under study can be incorporated in the model via the differential regularization.
