expandBasisFunction: Calculate a linear combination of arbitrary basis function

In MFPCA: Multivariate Functional Principal Component Analysis for Data Observed on Different Dimensional Domains

Calculate a linear combination of arbitrary basis function

Description

This function calculates a linear combination of arbitrary basis functions on domains with arbitrary dimension.

Usage

expandBasisFunction(scores, argvals = functions@argvals, functions)

Arguments

scores	A matrix of dimension N x K, representing the K scores (coefficients) for each of the N observations.
argvals	A list representing the domain, see funData for details. Defaults to functions@argvals.
functions	A funData object, representing K basis functions on a domain with arbitrary dimension.

Value

An object of class funData with N observations on argvals, corresponding to the linear combination of the basis functions.
