need matlab code for these questions, make sure it works on r2016a

s for each of the problems shown below: The stress concentration factor for a stepped circular shaft shown in Figure 5.23 is approvimated by where c and a are give in Table o obtain two expressions, one for cand the other for a, as a function of Dil in Iwo ways (l) with a fifth order polynomial and (2) with a spline, For both methods, compare the values of K, obtained with the two sets of litted values to those obtained with the original values given in Table 5.6.
