Question:

Use Newton’s divided difference interpolation to find erf(0.5) based on the data provided in the following table. You need to go up to the fourth divided difference. Compare your result with that obtained from typing erf(0.5) at the MATLAB command prompt. X 0.2 0.358 0.41 0.537 0.6 erf(x) 0.222 70 0.387 35 0.43797 0.55241 0.603 86
