Write a Matlab function program der4x y which given the valu

Write a Matlab function program der4(x, y) which, given the value of a function at five base points (x, y), uses a fourth degree interpolating polynomial so evaluate the derivative of the function at the central base point. Use the Matlab utilities polyfit, polyder and polyval to do this. Use this function program to solve the following problem. Calculate the enthalpy of vaporization of water at 50^degree C to at least 5 significant figures from the Clapeyron equation
