I done with the first 3 but for number 4 I got an error ( matlab said the vectors must have same length) here is the code that I use
x_nodes = [1977 1980 1990 1995 2000 2005 2010]; y_values = [698840 907701 3233313 4973983 5674178 7932710 13561623]; x_eval = [1960 1985 2015]; divdif_y = divdif(x_nodes,y_values) p_eval = interp(x_nodes,divdif_y,x_eval) x = [1970:1:2015]; y = interp(x_nodes, divdif_y, x); figure(1), plot (x,y,x_nodes,y_values)
Thank you
