Problem
1. How would you test for contradictory equations when using eliminate? How about identical equations?
2. Of what use would Gaussian elimination be on a system of M equations in N unknowns, with M < n?="" what="" if="" m=""> N?
3. Give an example showing the need for pivoting on the largest available element, using a mythical primitive computer in which numbers can be represented with only two significant digits (all numbers must be of the form x.y x 102 for single-digit integers x, y, and z).
