weights {ivmte}

Generating splines weights

Description

This function generates the weights required to construct splines of higher order. This function was coded in accordance to Carl de Boor's set of notes on splines, "B(asic)-Spline Basics".

Usage

weights(x, knots, i, order)

Arguments

x

vector, the values at which to evaluate the basis function.

knots

vector, the internal knots.

i

integer, the basis component to be evaluated.

order

integer, the order of the basis. Do not confuse this with the degree of the splines, i.e. order = degree + 1.

Value

scalar.
