The second function, called poly value, should read in the table of divided difference values generated by the function divdiff, the x-vector, and a vector t. The output of the function are the values of Newton's polynomial computed at points given in the vector t. This means, your file poly value. m should start with the following few lines: function v = poly value(a, x, t) % input: a = Newton's divided differences % x = the points for the data set to interpolate, % same as in divdiff. % t = the points where the polynomial should be evaluated % output: v = value of polynomial at the points in t
