Values of Basis Functions or their Derivatives

DESCRIPTION:

A set of basis functions are evaluated at a vector of argument values. If a linear differential object is the values are of the result of applying the the operator to each basis function.

USAGE:

eval.basis(evalarg, basisobj, Lfdobj=0)

REQUIRED ARGUMENTS:

evalarg
a vector of argument values.
basisobj
a basis object defining basis functions whose values are to be computed.

OPTIONAL ARGUMENTS:

Lfdobj
either a nonnegative integer or a linear differential. operator object.

VALUE:

a matrix of basis function values with rows corresponding to argument values and columns to basis functions.

DETAILS:

Note that if a linear differential operator object is supplied, the basis must be such that the highest order derivative can be computed. If a B-spline basis is used, for example, its order must be one larger than the highest order of derivative required.
