Matlab code please

1. Consider the stress-strain relationship given in the table below: (a) Use quadratic interpolation to find s when e = 0.04 (b) Use linear interpolation to find e when s = 50 (c) Use spline interpolation to find s when e = 0.03 0.06 0.08 Strain, e 0.02 0.05 0.1 0.15 0.22 0.25 Stress, s 40 37.5 43 526055 Table 1 Stress-Strain relationship
