roots_

roots_(c) does not return zero when c(end) is nonzero.
Matlab's roots function does not satisfy the condition that roots(c) should not return any zero roots when c(end) is nonzero. For example, roots([1,1,1,1e-32]) incorrectly gives a root of exact zero. roots_([1,1,1,1e-32]) gives the correct root of -1e-32.
