A related question:
Code efficiency-wise, would it be quicker to just x2=abs(x2), rather than
searching through eps values? The error introduced would probably be small.
Is there a quick vector way of setting all values less than eps to zero,
rather than searching the vector with a for loop?
Just curious.
