Only part 2 in matlab.

3. (20 points) Computer project. Write computer code and implement (1) the power method; (2) the symmetric power method; (3) the symmetric inverse-power method. Test the methods on the following matrix. / 4 1 1 1 1 -1 2 0 Use tolerance 10 5 and xo - (1,0,0,0)7. Show the approximate eigen- values from the iterations. 3. (20 points) Computer project.
