File Information
Description	This is still a work in progress, having trouble setting tolerances but setting the number of iterations seems to work fine.
MATLAB release	MATLAB 7.11 (2010b)

12 Oct 2011	Andrew Knyazev	"Number of iterations will be increased accordingly in order to meet the set tolerance value" - in other words the "ite" parameter is always ignored. The code never stops if the tolerance is not met.
