I need a MATLAB code for Newton's Divided Difference for the questions below:

a. Use Newton's Divided-Difference to construct the interpolating polynomial of degree four for the unequally spaced points given in the following table:

x	f(x)
0.0	-6.00000
0.1	-5.89483
0.3	-5.65014
0.6	-5.17788
1.0	-4.28172

b. Add f(1.1) = -3.99583 to the table and construct the interpolating polynomial of degree five.
