ADSIMP: A Matlab function for subregion adaptive multiple integration of a vector of functions over a simplex or a set of simplices. This software uses the integration rules and subdivision methods described in the paper by Alan Genz and Ronald Cools, An Adaptive Numerical Cubature Algorithm for Simplices. DESCRIPTION Computation of integrals over simplical regions. adsimp is a driver for the integration routine SMPSAD, which repeatedly subdivides the region of integration and estimates the integrals and the errors over the subregions with greatest estimated errors until the error request is met or MXFS function evaluations have been used.
