Question:
(a) Determine the values of ||H||1 and ||H-1||1.
(b) When the system Hx = b is solved using MATLAB and the computed solution xʹ is used to compute a residual vector r = b - Hxʹ, it turns out that ||r||1= 0.36 Ã10-11. Use this information to determine a bound on the relative error
where x is the exact solution to the system.
