Computes the exact integral of a polynomial p(x) over an m-dimensional simplex S in n-dimensional space, 1 <= m <= n. The methods are exact for polynomials, no approximation is used. The only inaccuracies possible are in the floating point evaluation of knots, coefficients, evaluation of the polynomial, sums, and products.
adsimp is a translation of Alan Genz's matlab program adsimp.m to adaptively integrate over a simplex. The other functions listed below are all called by adsimp. These functions are used internally; use at your own risk.
Adaptive integration of a function f(x) of n variables over an m-dimensional simplex S, 1 <= m <= n. More generally, f can be a vector valued function and S can be a list of simplices.
Computes an approximation to the integral of a function f(x) over a simplex S. This is an R translation of the matlab function grnmol.m which was written by Alan Genz.
LasserreAvrachenkov implements the exact integration formula for a homogeneous polynomial p of degree q. The other functions are helper functions for that.
