Evaluate Monomial Basis

Description

Computes the values of the powers of argument t.

Usage

monomial(evalarg, exponents=1, nderiv=0, argtrans=c(0,1))

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.

argtrans

Linearly transform an argument before constructing a basis. The first element is the shift in value and the second the scale factor.

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)
