simpson.coeff {etasFLP}

Computes Simpson integration rule coefficients

Description

Computes Simpson integration rule coefficients.

Usage

simpson.coeff(n)
simpson.kD(n,k=2)

Arguments

n

number of points of the simpson formula a single dimension

k

number of dimensions

Details

simpson.coeff computes the coefficients of the standard Simpson rule (for unit spaced points), according to the sequence (1+4+2+4+...+2+4+1)/3 for each dimension. simpson.kD expand the formula over a grid of n^k points in k dimensions.

Value

a vector of n coefficients (for simpson.coeff), a k-dimensions array with a total of n^k elements for simpson.kD.
