Set A = diag(10:-1 : 1) + 10* diag(ones(l, 9). 1) [X,D] = eig(A) Compute the condition

Question:

Set
A = diag(10:-1 : 1) + 10* diag(ones(l, 9). 1)
[X,D] = eig(A)
Compute the condition number of X. Is the eigenvalue problem well-conditioned? Ill conditioned? Explain. Perturb A by setting
A1=A; Al(10.1)=0.1
Compute the eigenvalues of Al and compare them to the eigenvalues of A.
