1. The problem statement, all variables and given/known data Compute the condition number of the following matrix: | 1 1 | | E -E | where E<<l infinity norm. 2. Relevant equations l infinity norm: ||x||infinity = max |xi| where i goes from 1 to n. Condition number: K(A) = ||A||*||A^-1|| 3. The attempt at a solution A= | 1 1 | | E -E | A^-1= | 1 -E | | -1 -E | ||A||infinity = max(2,0) = 2 ||A^-1||infinity = max(1-E,-1-E) = 1-E K(A) = 2(1-E) = 2-2E Is this right or am I completely off? Thanks!
