1.

Compute the largest eigenvalue of the matrix

using the power method.

2. In this problem, you will compare the execution time and accuracy of eigqrbasic, eigqr, eigqrshift, and eigb.

 Execute the following:

Comment on the results.

 Using the MATLAB sort command, sort
 and compute E = sort(eig(A)). Compute the accuracy of each of the four functions against that of eig by computing
