monomial: Evaluate Monomial Basis

In fda: Functional Data Analysis

Description

Computes the values of the powers of argument t.

Usage

monomial(evalarg, exponents, nderiv=0)

Arguments

evalarg	a vector of argument values.
exponents	a vector of nonnegative integer values specifying the powers to be computed.
nderiv	a nonnegative integer specifying the order of derivative to be evaluated.

Value

a matrix of values of basis functions. Rows correspond to argument values and columns to basis functions.

Examples

# set up a monomial basis for the first five powers
nbasis   <- 5
basisobj <- create.monomial.basis(c(-1,1),nbasis)
#  evaluate the basis
tval <- seq(-1,1,0.1)
basismat <- monomial(tval, 1:basisobj$nbasis)
