@Carl Love Thanks for the edits! The procedure is acceptable now, but it doesn't seem to be working quite right. When I run the procedure Kermarkar(evalf(<<-2 | 2 | -1>>),evalf(<1 | 0 | 0>)); I get a 3x1 column vector with each entry as HFloat(undefined). Any ideas on why this may be?

Does this indicate some sort of pathology like division by zero somewhere along the line?
